- Someone on the Science Festival committee at my kids' school had the idea for a twist on the classic egg drop. They just needed someone to BUILD their idea.

The TED Talk Marshmallow Challenge I mentioned:
• Peter Skillman Marshma... - Věda a technologie
This is a great example of solution by iteration. In retrospect I may have been time ahead to do a little math up front, but was afraid it would tell me NOT to do the simple PVC pipe version which I really wanted to try. But this is the reality of engineering. We can't afford to calculate/simulate EVERYTHING so we make tradeoffs, examine a few failure modes and make a prototype to see what happens. I HIGHLY recommend the TED Talk referred to in the video. Incredibly enlightening about kindergarteners beating educated adults in the Marshmallow Challenge. See link below.

That was awesome! Your editing is great, but I have a quick unsolicited note about the audio levels - It was difficult to understand what you were saying over the sounds of things like power tools.
That spaghetti challenge reminded me of of Destination Imagenation (we started doing Odyssy of the Mind then swapped) We used to get challenges like the spaghetti one and where judged on how well we did, and competed vs other shools. They also gave you a long term challenge, usually a engineering, or theatrical problem (maybe a mix of the both). I bet you would make an amazing judge, or coach for one of these events!
Was getting bunches of thoughts from your video…
First was thinking why you use two springs not like 4 springs, but got the point by the end of the video, the power is already big enough.
Second is my experience of playing with my slingshot from my childhood. I noticed that, lunch with the hold make far less distance than lunch with a final pull up, it’s a very big difference when I pull quick until release with no stop, lunch much further than pulled to the same spot, stayed for like 1 second, and then released. Don’t know if you can try it, i can’t explain what is going on, maybe some of the energy turned into heat while waiting on stretching…
Third is the stopping system. The spring power is really constant, why not cut a cylinder and a piston rod on your lathe, and using the air pressure inside it to stop the lunching rod… the air pressure build up makes the resistance add up quick, and will stop the rod much better than a spring… will reduce the impact really good, and you might need a air vent for maximum force reduction.
Well I’m kinda like a hobbyist than an engineer ( didn’t had any engineering school yet… )
And sorry for my explanation, looks really bad but I’m just bad at it… failed to make it better for years…
Your CNC mill to plasma cutter adapter is genius.
Yes!!!
That's a killer idea! You should do a stand alone video on that Quint!
The Dad force is strong with this one! Inspirational and entertaining all in one package. Excellent work!
😂 I couldn't go on without coming here to say that the idea of the plasma cutter milling lathe kill myself! 😂 It is ingenious for how simple it is!
10:55 not only am I laughing my ass off -- but that sawzall circle cutting jig...I can't even tell you I beside myself I am. brilliant, brilliant, brilliant, and thank you so much for all this, and specifically sharing that.
@ 6:24 Now that is just pure genius...
_Some eggs were harmed in the making of this video_
this is a great idea! its fun to watch pro engineers work on school projects like a joe!
Does CZcams have a Father of the Year play button? If so you totally just earned it.
Tough competition with Mark Rober.
After shooting a ball hitting the son😆
@@jonasnicolaysen8019 my father told me that means he loves me.
@@jckatz I'm sure he did ... :P
The plasma cutter with the mill setup is very clever!
I did a not-dissimilar project. Big springs to launch a shaft to hit a target. I went with an aluminum tube for the barrel. Mostly because I had one. For the bolt (which would propel the shaft) I bought an aluminium rod of suitable diameter. My choice was based on having a durable contraption. However after a few test shots, I replaced the rod with a hardwood dowel. Seems the aluminium rod had too much mass to accelerate adequately. Long story, short... Total success!
TWO thumbs up (it’s all I have) for your patience and perseverance to create this school project. Anything that helps motivate our youth toward S.T.E.M. careers is fantastic. Kudos to you, Sir.
The mass of the piston and spring is large and takes up much of the energy. There's a reason why ancient catapults had levers...
8:05 aluminum electrical conduit?
Brilliant plasma cutter with the Bridgeport!
before you put the wheel on i was imagining some elaborate wooden ratchet
That is awesome! I was really unhappy that I never got to do a science fair even once in my K-12 schooling. I come from a science-heavy family (there's a 300 ton telescope named after my grandfather) and really wanted to do things like this. Also, your house is about the same color as mine, and we live near each other! Thanks again.
I just love your videos! Thanks for sharing this with so much passion
Now make a adult version of this with explosives.
Im most impressed by your improvised CNC Plasma cutter.
your cnc plasma cutter is awesome. that's what got my attention.
Cool project!
Great
CNC Lathe to plasma cutter. I have never seen before.
That is really cool. I bet you had a blast at the fair.
Nice work.
Damn wish I would have thought of that when I had to do my science fair project lmfao I always did the potato clock 🤣🤣🤣🤣 good times 😁
If I were one of those kids, I'd build a contraption so heavy and large that the cannon couldn't launch it
this. is. so. wholesome.
Eggeslent eggxample of eggineering
you know what. sir! if you were my professor in engineering class. even if I'm an electrical engineer students. i would enjoy listening about basic of civil engineering and general engineering subjects.
Awesome videos :D the video showes a really nice increase from simple to complex while also improving the stability and performance. Very well done.
Hey Quint,
I just want to say, that I really like your videos. Full of technic but still very easy to understand. I am in the field of food-technology so I have some basic knowledge in the life sciences. Hopefully some day I will also get as crafty as you.
Keep up the good work!
Too bad you weren't my math teacher. I would've loved math, and probably learned to use it in my everyday life. I'm a father a father of 6 now, and trying to fix or build things all the time. As it is now, I wing it, and try to improve on what didn't work. Thanks for making what's complex, simple and enjoyable. Keep up the good work!
5:15 Don’t worry, you can always have another child.
Great job quint. Keep it up.
Good work! Get them trained up young, because no-one does apprenticeships any more. People need to know this stuff.
Like the old boy a zillion years ago who told me "You don't need a reconditioned alternator in your car. You need a 50-pence pair of carbon brushes", and then showed me how to change them.
If I ever stop learning new things (I'm 63 right now) just nail the friggin lid down :)
Awesome work, hope this goes viral. :D
Great video! Hope you are staying cool out there!
Love the scrambler! That is a great idea.
WONDERFULL!!!! Great dad award :-D.
Great work!
Loving your videos bro, keep up the good work
Great video!
Well that's basically how my Action Man (GI Joe if you're in USA) "mortar" worked back in the 1970s.
Amazing stuff!!!!
one of the coolest videos so far...you are a great father and mentor. keep the inventions going...Peace DVD:)
Great Video!!
Awesome video!
I still vote you the next Bill Nye you are awesome!! Love your Videos!
@@everettstormy I was once told if you cant say something nice dont say anything at all. You should try that.
Awesome!
Nice, try putting some chalk on the launcher to see if it looks like smoke :)
Awesome 😎
Sir, you are an amazing dad!
That replicator thing really got me for a sec
never say sorry .. especially for a prototype :) @Quint
This was AMAZING
I LOVE the way you explain everything! Even a noob can make something out of this knowledge! Thank you Quint!
Awsome
love ya!
I remember when doing the egg drop My teacher gave me this look like I was being lazy When I handed him mine because it was just a solid block of the densest foam I could find within the parameters that we were allowed and I cut a small hole in between the two foam layers to put the egg. my egg didn’t break but my teacher gave me that look🙄i’m almost 40 years old and it still bugs me to this day I thought I was being clever
The same way that a human is shot out of a cannon, with the bang & smoke used for effect
The stiffer spring you showed is better, despite having the same "stored energy", as most of the energy gets wasted in accelerating the mechanism. The stiffer spring you show is far lighter, and so, the terminal velocity that the mechanism reaches (for the same amount of stored potential energy) will be higher. (i'm guessing you are aware of this, but simplified for sake of the audience).
BTW, Tom Stanton (on YT) has done an interesting series on launching tennis balls with a trebuchet mechanism, whereby he tries to extract the laste millijoule of kinetic energy out of the trebuchet.
@@everettstormy Torque?? Pressure?? We are talking about a linear spring here.. not a torsion spring, not a gas-spring. Further, if the terminal velocity of the payload is the same as the terminal velocity of the mechanism, then any energy absorbed in compressing the pillow is irrelevant for the comparison.
Quick question if you were doing engineering now which branch would you choose
🔥🔥🔥
If only you could get some compound springs :)
Will you be upgrading your replicator to the latest model? I heard it makes 2 copies instead so that you can have a spare! Or go all out and go with their industrial model that makes 5!
Next year: CATAPULT
Hello!! 👋👋
Neat
That replicator is pretty nifty. Why don't you make a video on how you modified your 3d printer to do that lol.
On a completely unrelated note, you son got a nice haircut.
Did you really just saw a plank with the powercable right under where your saw is???
I did this at a previous school, but went with a propane powered potato cannon. Here was a demo video I did to test the idea: czcams.com/video/GVMj5BYJ1iY/video.html&ab_channel=spudafett Schedule 40 3 inch pvc pipe just happens to allow a PERFECT fit with pringles cans. I had my students build their devices within a pringles can base and then we launched them outside on the football field. At least one device did survive... I wish I still had the video of their launches. Most just disintegrated as it left the barrel!
Nice work!
👍👍👍👍👍
Next year cannon that shoots kidns!
Hey mate I've had a question cause you remind me of my dad who loves building things for science haha, what 3D Printer are you using? I really want to buy him one to help him along :).
Flashforge creator pro but you can get by with something cheaper like an Ender.
2:25 $6.99 for a single tiny spring?! Plus the lumber, PVC pipes, etc. Seems like you could have bought a Honda Civic with the cash it took to build your cannon.
Yeah but a Honda won't bop the son and the head, that is priceless
How the heck does the mechanism work? I don't get it?
Anyone else thought he said TikTok instead of TedTalk?
No
Is that a Calvin and Hobbes brand replicator? Your videos make more sense now, you must have gotten a hold of a Cerebral Enhance-O-Tron.
My first science fair was my 8th grade. I did mine on Nikola Tesla.
What a waste of valuable toilet paper
i think rubber bands would of worked batter
If
Ohhhhhhh... you should have explained the two science fair sections at the beginning, cuz I was starting to feel bad about you doing all the work for your kid's project for most of that video...
7 dislike
7 😡 chicken
*William Osman would like to know your location*
What an awkward weird nerdy guy....It's cringey watching your videos. You instantly got my like and sub. Keep 'em coming Quint.
Can I buy the replicator on eBay? I feel it could be useful when combined with my money collection ;)
:D
Typical scope creep on this project. Now, multiply this by a few tens of thousands of dollars and convert it into an embedded electronic control system. Oh, yeah -- start with a fixed bid that the end customer refuses to acknowledge was insufficient to begin with, and which the broker won't challenge for fear of losing future business from the end customer. Add more electronics and software as needed, all at my expense. Finish just before the drop dead date. Deliver and get nothing extra but a pat on the head.
My life.
I wish hair stayed on your head
Awsome
