- Was the second one too much of a trick? Let me know in the comments. I feel like it was fair because you should try to understand why the video would be true, but let me know what you think.
Here's a list of questions answered in this video:
1. Does a spiral of aluminum foil spin on a stick when you light a candle?
2. Can you make chalk using flour and crushed egg shells?
3. Can a hair dryer propel a toy car?
4. Can 3 matches hold up a heavy 2L bottle of water?
5. Do match tips sink when you squeeze them inside a full 2L bottle of water?
6. Does an egg get sucked into a bottle when you light a match and throw it inside?
7. Does adding salt to hand-sanitizer make it combust when brought into contact with a paper towel?
8. Can an empty can float on top of pool water without any assistance?
9. Can you take an egg shell and remove all contents to make an egg volleyball? - Věda a technologie
Might aswell rename it to spot the reverse video
Honestly true lol, I need to work on coming up with more variety of fakes.
@McB That's a fantastic idea, I'll probably do that

I try to avoid looking for video tricks to make it more fun but sometimes it’s hard to avoid it
@@JaDroppingScience I agree. And I even find myself trying to figuring how I would fake something before I think about how it would work scientifically.
However, these videos are a clever and original way of inspiring people to apply reasoning and lateral thinking to science and that’s awesome all by itself. So keep up the good work! 👍
I’ve seen like 100k of these comments lol
Just noticed "Purell-ly a distraction" on a second watch, nice one.
I remember when I was a kid, the neighbors had this beautiful contraption they'd bring out on Christmas that was powered by candles driving turbines just like in the first clip.
I've seen a couple of things like that too. One of them had angels that span round and rods that tapped bells once spinning fast enough.
We have lots of those pyramids! They're very popular in Germany
Me to! My Grandparents a contraption that made bells go, ding, ding, ding. Loved it!
A classmate wrote a research paper about those haha
My parents both had this in their childhoods and carried the tradition on! They (or at least the ones we use) are called angel chimes because there are little metal angels on them that ding a bell as they turn. Weirdly, one of my parents is from England and the other is from the US and neither of them are from areas where these are particularly common, so I'm now mildly convinced I'll only be able to fall in love with someone who also had angel chimes at Christmas in their childhood.
Here's a link to a short I made explaining the match balancing one: czcams.com/users/shortsRt6oUgEy_jU?feature=share
Thanks!
I was gonna say, I ain't never seen a hair dryer do that shit before and I love studying physics
Smashed it again. Got all three🎉
Thanks for making me feel clever 😂
for the first round, I literally have no idea, they all seem true, and I've seen basically all of them done before... I guess the chalk is fake?
well, I guess I'm wrong then, although, my hairdryer is really strong, and could probably push a toy car... in fact, let me test it! then maybe I'm not technically wrong!
ok, so my hairdryer can EASILY duplicate the video clip _in real life,_ your clip is not a good option for a trash!
ok, for round 2, the second one, the floating matches is fake, water is incompressible, and the match tips should still sink regardless of pressure. (unless they have gas bubbles inside)
round 3, OK lol 1 is fake, I know chemistry! hand sanitizer flame? too late, I already tried it at home months ago xD
As clever as always. Good job!
I love these videos and they are a completely original idea too. keep it up!
i love this series. i don't find a lot of content on youtube that makes me actively think critically. i don't get a lot of these right, but i'm telling myself this is because you're good at this and not because i'm gullible LOL
2/3, that first one really got me (but now I have a new use for egg shells... well... at least I would if I weren't allergic)
Will be updating this as I go
1st round: 2nd fake, would love to use my excess egg shells for this though
edit: no way, keeping my egg shells for future usage rn
2nd round: i feel like 3rd could be fake, but if its real I have 2 new things to do with my eggs
edit: I have 2 new things to do with my eggs
3rd round: hopefully 1 is fake, I could see myself accidentally doing this 😬
edit: I now have 3 new things to do with my eggs
1/3 I failed this one 😅
Good episode, should be called 2 truths and trash: egg edition
Haha your commentary made me laugh, well done
I didn’t spot this pattern. Congrats u did lol
I‘m glad you have three new things to do with your eggs
First round was kind of crap since all three work, it's just that either the dryer's motor was too weak, or the car it was on was too heavy for the thrust to overcome inertia. Try that same experiment on a boat floating in a pool, it works great.
I love your science vids and learn new things every day, me and my parents always can’t wait for new vids/shorts because than we watch your videos and vote (not in the comments) and whoever wins doesn’t have to do the dishes. But if you don’t upload for a period of time that schedule stays the same so we are always (not) praying for a new vid.😂 And if you got a motible question vid like this we do it pont based😁
I actually laughed out loud at the hairdryer thing
i love this series
I always get tripped up on the ones where the physics are correct but there's not enough energy in the system to do what is being claimed.
Wooh! I got two of them wrong! Which means I learned something new! Thanks!
Round 1: I know 1 and 3 are true, so I'm ruling out 2 by process of elimination. (Okay, I knew 3 was correct in principle, but it didn't occur to me how weak hair dryers were)
Round 2: It doesn't matter the arrangement of the matches. The top match in 1 is experiencing a force greater than its weight ahead of a fulcrum. There's gonna be a torque on it. There has to be something on the table holding the match down. (I'm completely stumped. I suspect it has something to do with that quasi-triangular formation, but even then I don't see how the torque isn't affecting the entire system.)
Round 3: This is a tough one, but I know 3 is a real thing, and of the remaining two, 1 feels less believable. So I'm going with 1. (How did I get a question right about the one subject I failed in college, while missing the two questions on the thing I actually have a degree in?)
Regarding the matches, pay attention to where the center of gravity is. It's under the table. This is basically the same idea as one of the earlier videos involving some silverware and a toothpick.
idk bro, but you're not wrong with the hairdryer, I made the exact same setup myself, and my hairdryer EASILY duplicated the faked results in the video.
also, for the balanced matches, I'm a noob at geometry and stuff, but I understand the simple physics, (and also that its harder to fake that one with editing than with the others)
the top match is pivoting at its center, and if it were to pivot downward in the process of falling, it would be pushing down on the match underneath it, which consequently pushes the one under that. this last match is held by friction, and its resting in the widest portion of the loop of string, which is held in tension by gravity, so if it moves downward, it gets forced into the narrower portion of string, which doesn't want to happen since its in tension, and wants to snap together to make a straight line. the pushing down force would also push sideways a little, pushing the bottom match away from the camera, and this makes the loop of string no longer straight, but bent, which is not the quickest path from A to B, which means it would have to pull the bottle upwards to remain the same total length, which also does not want to happen, since gravity is pulling the bottle down. its a bunch of opposing forces that have all hit equilibrium.
you got me on the first one lol
If the salt hand sanitizer trick worked you'd probably get burns from using hand sanitizer.
The one with the matches balancing the water bottle is sick, didn't think that one was real.
I love this
i love the matchstick heads rising one because it can both be a truth if you use the actual fact and a lie if you just reverse it
I find the last one weird since it does impact its velocity, just not as quickly.
One out of three, got absolutely obliterated by this one.
First time ever getting a 3 out of 3, let's goooooo!!!
I almost messed up on round two because I've seen videos displaying the trick where squeezing a bottle makes particles inside sink, and I thought oh that's gotta be true, but at the last moment I went wait didn't squeezing make them sink, not rise?
1 for three. I got fooled by the simplicity of the hairdryer claim. And I know the squeezing bottle trick works with pen caps, it didn't occur to me that it obviously wouldn't work with something naturally buoyant.
I haven't tried it, but wouldn't the squeezing bottle thing make pen caps sink, not float? Since the air inside them would compress, and they would partially fill up with water, making them denser and therefore sink
@@Einstein-wasnt-all-that-smart I had to look it up to check. It's the "Cartesian Diver" experiment. And you're correct, it sinks when squeezed, I got it mixed up.
For the last one: How does the egg close itself? I honestly thought it was the fake one cause it could’ve been a deflated white balloon
it has two layers. the shell is only one of them. you can in fact, peel an egg
@@citratune7830 ofc but I meant if there’s 2 holes in the shell how does it keep the air in after you blow into it?
I vote 1. I'm pretty sure the air currents would move it, just not that quickly.
I got all three of them!
Round 3 was the hardest but I knew that the egg was real so I just had to think until I realised the can makes sense
2:40 you can also get one of these by having calcium-deficient chickens, which don’t produce enough calcium to form a whole shell.
I would not believe that you can balance a can in water like that... Oh well, guess I need to go buy some soda and get myself into a pool
All correct let’s go!
Purell-ly a distraction. Yeah, I caught that lmao
1:04 This one seems so unlikely that I completely missed how obviously fake the next one was lol. Tricky.
"Purelle" LOL
yes! I've got 3 correct in a row!
Purell-y, nice
I love your content
Only got the hand sanitizer wrong
Always love your vids!
Got 3/3 correct!
The unedited Round 2 video 2 represents how submarines work.
any european *should* know the candle one, it's a popular gift-thing and can be found in many a christmas market
only got one wrong, being the floating match-tips, because I knew about the trick but forgot which way it worked. logically, i shouldve figured it out. increase density, less dense stuff sinks
I got 2 out of 3. Best I’ve done so far haha
I got the first one right, but with the wrong reasoning. I just thought the cord would make an imbalance or something else that would cause the car to fall over.
I mean, the hair dryer one was kinda tricky because the principle is still true. Fair game though, I didn't think that the hair dryer would be too weak. It also depends on the friction of the wheels on the car. Definitely a tough one at a glance.
Random fact : i just realized laser lines visible on water. So thats mean every laser on cartoons are filmed underwater
The first one threw me off. As someone who is into physics, I thought the chalk was fake as I assumed it would turn back into powder after It dried
Match one I think or the egg bottle one.
Yes
There are definitely hair dryers strong enough to pull that off
the 3rd trick for the last three was concerning
I thought he replaced the sanitizer with sulfuric acid 😂
this is getting much harder
I thought that he was making a makeshift blunt for number 2 ngl
I knew the hand sanitizer one was fake because i nearly burned myself as a kid using invisible fire
i think number 1 here was a little too tricky, it's not like we knew how strong your hair dryer was or how light the car was
With the hair dryer I thought we where spotting the false fact not video, as that is how rockets work, correct.
Wow
The last round got me. I reasoned that 1 could be fake due to usage of a different material to light the alcohol, but I also thought 2 could be fake since you could have easily attached something in the water to hold the can upright. 🙃
invisible fire
>:D
Ever heard of the ocean? Salt and water is just fine
match holding bottle
Honestly I guessed the second vid for round two, but not because I thought it was in reverse. Just seems unreliable in a way that's hard to describe.
Round3: 3
2/3, Didn't get the last one.
I remember I ate the bouncy part of the egg at video 3, it was between the shell and the egg and it’s edible (WARNING! I ripped of the bouncy part myself, I don’t think if you eat it with vinegar would be safe.)
Why wouldn't it be safe? Vinegar is not toxic.
how was i meant to know how stong the hair dryer was?
guessed correctly
Omg!, I tried this at home!! Should I turn myself in? 😮
6 wrongs in Total. I feel stupid
3,2,1
Actually, the hair dryer thing was not entirely accurate. The hair dryer wouldn't propel the car IF it didn't have enough pressure at the outlet side of the 'pump' to overcome the rolling resistance. Can't tell that from our side (viewer) of like 2 seconds. The pressure thing does work, if is enough to overcome the resistace.
So ... That one was 👎.
Everything else I've seen you do has been 👍
:)
The first lie is very deceptive, it's a true thing that can technically happen, there's nothing "wrong" about it.
paper towel acid
You are wrong about the hair dryer. Even a weak hair dryed would be able to push a car as long as the rolling resistance is not to high. And rolling resistance can be made very low. You just chose a bad dryer/car combination.
Saying, "Please don't try this at home", mean that I HAVE to try it ay home,{I'm that curious}
3 is RUBBISH on the 1st one
18/18 So far
3
Round 1 is such BS. That particular hairdryer may not be able to push that particular toy car because of the axle friction or something, but obviously a hair dryer does exert a force that could be used to push an object. How could we possibly know that the hair dryer was very weak?
@JaDropping Science since you're on your way to get so popular you won't read most comments anymore- with every video you can make crazier thrash throws, till we finally end up watching you throwing it to a garbage truck from empire state building
I know it probably won't bring new audience, but hey here's one of your viewers dream
PS. English is my second language so please don't judge me or I will come to your house
haha, yes I am planning to update the intro every 10 episodes or so
The egg thing is definitely real
2/3
3 for 3 baby
3 2:14
I ace it
1 is ”not” fake
2
Your hair dryer is weak. Mine propels the car.

You know what would be cool? If you made a marathon of these videos but cut out all the true ones except one so it would be like 30 truths 1 trash and you need to spot the fakr
Round 1: I’m not good in physics, but I think 3d is fake. Second is 💯 right, because there is calcium in egg shells
Round 2: idk perhaps 1st is fake, 3d is right 💯
Round 3: 1st one
I'm gonna guess number 2 is false, since the others seem true, unless you say 1 is false because you said the heat rises, instead of the hot air rises.
i cannot spot the fake
i watch too much nile red to lose this game
