If you want to confuse the crap out of housekeeping, leave it in the hotel room when you finally check out.
Orxenhorf with a pair of scissors and a note saying "Do not cut rubber bands"
then you'd need hidden cameras to see how long it takes for them to crack.
the camera will be hidden inside the Hexastix itself

At first I thought it was gonna be a Parker Square, but then he succeeded.

It became a Parker hexastix instead lol.
Numberphile reference on point.

I know right. What witchery and hexacraft is this?
Carefully this doesn't get flagged for being inappropriate, is this not a bit too hexy for youtube?
ben Jovi good one! lmao!
It's too edgy
shows waaay too much 'insertion' lol.

Anyone noticed that one pencil with the horrifically off-centre lead?
Ganaram Inukshuk He did opt for the cheaper pencils.
Only one?
i think it was more like one that had the graphite centered... sculpture is about the only thing they are good for..
He should not have bought the cheap ones.
That's because it was a Parker Hexastix.
I'm going to try this with toothpicks.
Well, it hasn't happened yet...
You'd need amazing coordination to be sure you put the toothpicks below/above the right ones. Do they even make rubber bands small enough to do that?
I'd suggest the ones used for braces.
Just twist it a bunch.

That is so cool!! If you ever need wood pieces for a future math art/puzzle let me know, I'd love to collab!

Hey Willem! Good to see you over here as well!
That cool may help to find pi
What an absurd coincidence! I'm writing this on my couch about half a mile from that staples!
Didn't think anyone ever came to Vermont :D
Sam Hays, are you going to see him at the show in New York?
That's why people like to visit Vermont; nobody goes there.
Well , that's a bit complicated . . .
Lol same but I'm like 5 miles away
I'm from Vermont as well, don't know exactly where this staples is though. It looks familiar.
Having future matt at the beginning was clever as all get-out, good job on hooking me immediately. Which, as a medium-long-ish time subscriber, you didn't have to at all, but still.
72 steps and easy does not goes very good together
There are varying degrees of difficulty when it comes to 72-step methods. This particular 72-step method is of the easier ones.
Each individual step is easy by itself.
Is how I think of it.
Arturo a writing the letter a 72 times is a 72 step process but still pretty easy to do.
Arturo a English and you dosent eeetheer.
How to walk up stairs in 72 easy steps?
I wonder... How many pencils can one safely take out from the finished hexastix structure without collapsing it?
That's a complicated version of Jenga you got there.
Hexajenga?
QUICK SOMEONE PATENT THAT!
Then you have to rebuild it every time you play.
Maybe you can make an octahedron with holes for where the pencils go which you can pull the sides off. Like a polydron.
+BetaDude40 I thought of that the moment I saw it completed
+Yevhenii Diomidov thank you, I appreciate
Matt says "I prefer Pi."
Do not read his quote backwards. I know it's an English Language joke!
U atrefer Tau
um
y u no work
IP REFERP I . . . hmm. . . . PI PREFER I. . . hmm. . .
The first one, IP REFERP I, if you join the P in IP to REFERP and you join the P in REFERP to I, you get "I PREFER PI"
It sounds the same backwards too.
4 years later and it's still a good video. Nice work Matt!
Oh Matt. Only an adorable little nerd such as yourself would be THAT excited on visiting Staples. :P
Never change, you magnificent Brit.
ZeroHero3d (sniff) I wish he were a Brit, unfortunately he is an Aussie 😢

Plexxar Yeah sometimes they can be hard to tell apart even as an Australian myself so I understand the confusion
+Plexxar all g xD
You're correct, just late
"I'm a maverick when it comes to pencil structures" ...a line i never thought i hear...or even existed =)
Thanks, Matt. You make the world better, one maths video at a time 💕
Thank you so much for making your theme available to download. Always wanted to add it to my cycling playlist.
Can I say that Staple make HORRENDOUS PENCILS? Like, wow, the lead is not even near to being centered!
Graphite

noun: lead; symbol: Pb; plural noun: leads

graphite used as the part of a pencil that makes a mark.
"scrawls done with a bit of pencil lead"
@@sacredgeometry the definition holds in terms of conveying the message however definitions stem from widespread usage and while undeniably lead is used to refer to the graphite in pencils The issue I take is that I referring to one material as another in this context to be unjustified. Being shallow and pedantic is the dream of all who roam the internet
The vast majority of people will not know the context of why it called lead and hence the practice of referring to it as such often leads to misinformation
Staples just sells the pencils. He specifically bought the cheapest brand they had. The other more expensive ones are much nicer. Dixon Ticonderoga pencils, the ones in the green boxes, are my pencil of choice.
2:52 R.I.P. pencil leads
Irixio Zalaniar
Haha, I thought that too. Also, did you notice how off-centre the leads are at 3:11? They must be really cheap pencils!
Does dropping a pencil break the 'lead' from the inside? I've never heard about this before.
Yes, graphite is incredibly fragile and with cheap pencils like those there will be bubbles throughout the entire thing which would make it shatter even more easily.
I did this with my kids (4 and 6) and they loved it. They got to do lots of participation putting in and taking out pencils, and they got super excited when we got to each stage and the next hexagon was made. We spaced it out over the course of a day, returning to it occasionally. We also made some hexaflexagons to make it a hexagon themed day.
I just made one of these, and I was inspired by your video. I relied on Alejandro's instruction for the filling out of the four pencil sections. I followed your example of just feeling it after. I bought two 24 count boxes of pencils, and one 40 count. The extras certainly helped.Here's to you, Maverick of pencil structures.
YES FINALLY!!!! I've been waiting for this theme song forever!!
can I buy the song for a negative amount of money?
"any nonzero AMOUNT" - as far as I know, an amount is a nonnegative real number. Still, I don't think I can pay exactly 1/pi dollars for that song.
i bought it for an imaginary amount
Do you have imaginary dollars? You wouldn't want to get into imaginary debt. Especially since the compound interest from it will follow a sine curve.
I really enjoy your uploads. Good work Matt and best of luck for your MoMath event on Sunday.
So good to meet you in passing Matt! Thank you for your graciousness to a random stranger. Enjoy your trip, it was a brief random pleasure.
What if you remove the rubber bands? Does it fall apart?
watch?v=GanFc6Llf9I
I also want to know the answer to this. (I may be tempted to build one to find out..)
Jonathan Ståhl
the gravitational pull will make it collapse into a singularity and suck in everything around it.
Of course it would fall apart
the rubber bands are the only things holding it together
Yes, the tension from the rubber bands is what is keeping it together.
Non zero value...?
-$299.99 please.
Nonzero amount :)
An amount is a nonnegative real, so... Sorry, but nice try.
Thanks for the tune, Matt, that was a nice and generous move of yours to share it for free. I really appreciate that :)
Great editing, fun commentary, and hilarious comedy. Another great video, Matt! I enjoyed it.
Words cannot describe my respect for that intro...
George Hart rocks. And so does his daughter Victoria aka Vi Hart. Recreational mathematicians, unite the set of yourselves! :)
Lawrence Calablaster you are kidding me! Vi Hart is her daughter??? wow
Jeronimo san Yep
Wow, I didn't know Vi was his daughter either! That sounds like one hell of an awesome family line!
Yes indeed. It's a super-mathy family.
Just built it. Only took about an hour and was great fun. Really relaxing actually. Thanks for the project idea!
Another great video, Matt! Have fun in the US and good luck at Momath!
We just won hundreds of pencils as part of a comedy prize(360 to be precise) so this must be done now.
he traveled with his wife and the entire time she kept him busy with $20 worth of office supplies. This was my life growing up.
I just finished building my own hexastix. This was actually pretty easy, and shockingly fun. That's for the suggestion Matt!
I love the camera drop at the bit with the "cracked screen" sign. Clever.
what if you made a hexastix out of those bunches of 7 pencils
A Knife that's brilliant! Buy I think the pencils would have to be longer (3x longer).
Alex W ah yes, good point
Then it would be a level 2 menger hexastix and require 504 pencils.
You would probably also need longer pencils in order to do it bigger like that
Heptastix.
You have no idea how much I laughed when it was shown the hand was the future you.
Aaaa yesssss I've been waiting for the song for so long!! One of the reasons I love this channel :D
One of my favorite parts of any stand up maths video is thinking about what Lucie walks into at the end of the day
I love being able to go "oh I know exactly where he is!" Hope you got some Ben and Jerry's while you were here!
EsplodingBomb forget Ben and Jerry's. Did he get Kountry Kart Deli?
Matt, I'm going to buy your song for $6.28. How does THAT make you feel?!
+Remus Lupin Deeply conflicted.
Tau?
standupmaths if I bought it twice for $3.14 would that make you feel better?
I'll let you choose: £3,14 or £6,28?
I applaud the effort even as I renounce your im-pi-ety with regard to the true circle constant.
Just completed one! Very satisfying. Grandchildren really impressed! When I bought the pencils in Staples here in York UK, the guy said they had sold loads recently. I explained your project which could explain it! You should be on commission!
I came across this video a few days ago, and coincidentally I am currently traveling with my husband while he is on a business conference as well! What could I do but buy 72 pencils and some rubber bands at walmart and build one in my own hotel room! This was so much fun, and a good use of my time. THANK YOU!!!
This is going into my "to do" playlist
If you'd flip all the pencils in the green tube (so that the erasers are on the other side), you'd give your hexastix a really nice tetrahedral vibe.
Only watched the first 41 seconds so far. But that reveal was so epic! Loved every second of it.
Thanks for the theme song man. Was waiting for it for a quite a long time.
Hope you enjoyed your stay in Burlington, VT! I'm a mile away from that Staples!
3:10 worst quality pencils i have ever seen.
if u make hexy things with them it doesnt matter
YES thank you for releasing the theme song, it's awesome!!!
G.Hart's math sculptures are magnificent.
I decided to google who is George Hart. Turns out, he's dad of Vi Hart. Ok, that makes a lot of sense. :D
Btw, one day I will buy 72 pencils and build this ;D

Thank you so much for both a great video and the amazing song!
I just built this :D Its really cool and interesting, Thanks Matt. Ive Recently come across your videos and as a lover of maths and science ive instantly fell in love, Would love some more videos on 4D since thats still messing with my head
Get it shipped to Australia so I can use it as a centrepiece to my Matt Parker Shrine.
I'm Asian and I made it with chopsticks
Is AC suppose to mean actinium?
no ac means alternating current
no ac means asian chap
@@california_wang8078 No, AC means Assassin's Creed
no ac means acetyl group
Definitely a new favorite channel
This was awesome! With the captions on at the end it says [NOOO hexasticks] and [rip hexasticks] when it is hanging from the cord and dropped. Hilarious!
prefect gift for math teachers
lol yes
Correction: The hotel room appears to be decorated in the theme of innocuous.
I'd be interested to see the interior shape. I'm picturing sending one of those tiny cameras into it, or maybe filling it with an impression material and removing the pencils.
the intro was amazing. It caught me by surprise!
This is surprisingly easy to make. The last expansion is a little bit difficult if the pencils are a bit short, but otherwise pretty simple.
I'd love to turn it into a desk lamp. I would be interested to see what kind of shadows it would project.
If you turned into a desk lamp you wouldn't see the shadows. (If you were being sarcastic then, lol.)
I made it into a lamp with one 5mm white LED.

That is AWESOME!
Did he really pretend to drop his phone as an ironic poke at the cracked screen sign? At 1:34
Because that's fucking class.
Great spot. He's a bright lad alright. Old UK duffer here, just managed to tie my bloody arthritic fingers in a knot :)
Very very cool video and thanks for the song! I love that song!
That's cool! Making intersecting hexagonal tubes using hexagonal tubes!
is there a way to put a light bulb inside of it?
There must be! I'm very tempted to buy 72 pencils and some rubber bands and find out myself :)
LED?
I don't think so, it's completelly filled with pencils
L4Vo5 No it is not. He even stated that in the video.
L4Vo5 The four intersecting tubes in the final structure leave a cavity in the middle. So there is space, just no practical way of putting anything inside... Except maybe a good bit of superglue to support it all while you drill a hole into it.
i just bought a set oft 144 pencils for 5€ and a pack of elastic bands :D, this will be a nice project
'rubbers' have a totally different meaning in the US... they probably wouldn't work for this
Don't say it won't work because someone is going to make it work now
I'm a math teacher in the NYC area and I'll be at your show. I can give the hexastix a good home in my classroom.
I appreciate that as soon as the "Fix your cracked screen" sign came into view, you fumbled your phone. I thought you might end up needed the service.
Could you take out the rubber bands?
I was hoping he would do that. Perhaps the whole thing would just explode :D
Nope. They're the only thing holding it together.
Narwhocalypse These rubber bands will dry up and break one day. What a surprise for the new owner!
+Purple Perfect. I am going to do that.
I imagine it might be possible to cut the pencils to make slots to mount them onto each other without rubberbands
Did you use an Idaho potato or a sweet potato or mashed potatoes or roasted potatoes?
Love that you mentioned george hart... well done on the sculpture.i am gonna try 3 intersecting hexagons only but with 3 layers of pencils instead of 2. It’ll be a 75 pencil sculpture
Wow! I have downloaded the music theme , it's awesome ! Thank you .
for some reason I can’t get the image of waffle French fries out of my head whenever I see it
And that’s how you play Kal-Toh.
love these hotel videos.
Staples is one of the best smelling stores of all time. I got fond memories of buying computer stuff and games there in the 90's.
3:23 what a parker's pencil...
I have asked this a few times, hopefully being early will increase my response chances.
Mat, what kind of maths do you do? I study mathematics and I like Analysis and I'm taking Differential Geometry I and have been thinking of taking a Riemann Geometry course or something. Do you have any thoughts on that? :)
Great videos!
Has he responded to you yet?
Well, just did this with my 5yo daughter. She was much entertained. Thank you.
This video editing is on the next level
This video gave me my daily serving of grain.
Ok. You knwo what? Let's do the math.
You start with 7*4= 28 moves
you then move 6*4 =24 pieces
and add 6*4 = 24
Then move 12*4 =48
Remove 7
And add 6*4 = 24
Wich gives us a total of :
28+24+24+48+7+24 = 155 moves
He lied!
I've been waiting for another upload
I went for something more permanent and made it from Al rod and ran LEDs in it, makes a good hanging lamp for night and conversation piece. Thank you for the inspiration!
If you take off the rubber bands will it fall apart?
Yup. Somewhere there's a pencil on the "outside", held on by nothing but a rubber band. Once that falls off there's another pencil with nothing holding it on, then another, etc.
I think so. There's 2 completely unsupported corner pencils on each hexagonal face, and these would fall out. The loss of these pencils would cause other pencils to become unsupported, and so on and so forth.
The flipside of that is that as long as those 2 pencils are restrained on each face, it should remain 'stable', although the pencils might become so loose that they just start sliding out.
so you only need to glue 8 pencils total and it wouldn't need the bands?
I'm not sure it'd be as easy as gluing. The pencils would all rely on friction to keep them sliding out, and that friction is caused by the tension in the rubber bands. I don't think it would be that easy to replace it.
Besides, if you're going to glue any of them, why not glue them all?
1:55 - 'Chairmat' in the background, more like chairmatt amirite?
When I saw this video I went on Amazon and ordered a box of pencils and a rubber band ball, they just arrived and I now have a Hexistix, thanks!
the future you showing off the not-yet-built-by-you hexastix added a really cool touch to the video ;) subscribed and liked

I hit like as soon as I saw Future Max
I just went to the store and bought pencils and rubber bands, and built one. I followed your "just wing it" advice, and it turned out great. You're right about the process being satisfying, I wished I had bought 96 instead so that I could do another round, ha ha ha. Thanks Matt!
