[@OhhCrapGuy]

What's funny about the popcorn kernel one is that if it's connected to non-5GHz WiFi (also Bluetooth, and some mobile phone networks), the reason it doesn't work is more of an issue of order of magnitude and geometry than it is anything fundamental. Always remember that a microwave oven is just an angry Wi-Fi router in a cage.

Hell spinning the magnet like that doesnt even create a changing magnetic field.

[@OhhCrapGuy]

Oh, I just assumed it was a bunch of magnets that were attached NSNS in a circle around the axis of rotation, and while THAT would create a changing magnetic field, it wouldn't do jack to a flame. I also guessed the center of the magnet contained some fins, making a tiny fan in the middle that was making enough air flow to put out the match.

Does It permanently damage the record cos I realy wanna try this

[@cicianamumu]

@@Jack_Hoffmen I mean I would not try it on my records, maybe it does not and we are overreacting, but you can try it with other, less sharp things, like the corner of a sheet of paper, or just by running the turntable normally and not connecting it to any speakers. You can clearly hear the song by just the needle gliding along the track

[@Kalvinjj]

@@cicianamumu I would bet the stylus tip is much sharper even, but it's also the correct profile to ride on the record grooves and likely tracking with FAR less pressure. Testing it on a 78 RPM one likely would result in less wear, those basically just used steel needles anyway (that wore out quite quickly from what I've read/seen), and were played to begin with on much the same hardware as the test.

[@stevieb031969]

When exposed to a strong inhomogeneous magnetic field, flames can deflect, and they become more luminous. This phenomenon was first observed by Faraday1. The presence of “magnetic” and “diamagnetic” gases in flames contributes to these changes.

[@randysmith9715]

Item 3 is a common fire starter. It is usually made of wood and the tinder is attached to the end of the piston. I have made and used several different ones.

[@Tolinar]

Air vibration, flash effect. The phone is nonsense.

[@Tolinar]

Round two. The uneven object is probably real, I deal with similar behavior from shopping carts all the time. I'm not sure for the other two. Fire causes ionization but it's also possible the spinning object simply messed with the airflow. I'm going to guess the lemon juice is false, since there are lots of highlighters in the world and it can't be chemically true for all of them.

[@Tolinar]

Yeah that's what I thought I was seeing... a reductive effect. So SOME highlighters can be removed with lemon juice. Ok

[@Tolinar]

Round 3. Ah, a Gyroscope. Freaky. That's real. The Y-fitting is only partly true. You'll have to suck like a madman to get any fluid on your own, but if you both suck, it'll work. What the hell is going on with C? I don't know what I'm looking at so I can't assess if it's real or not.

[@Kobold_Green]

Interestingly enough, although the Y fitting doesn't allow 2 ppl to use the straw as they please, it will still work if they both suck on it at once, since it still creates that pressure imbalance

[@nienke7713]

Yeah, the card definitely felt more like random factoids you just need to know about, whereas the experiments can be known but can also be deducted with scientific knowledge, or even intuition can still help out there

[@k0lpA]

agreed, english is not my first language I don't know slang words for decompression and the one with vitamins is more about history or some kind of general knowledge.

[@GronTheMighty]

Easily the popcorn vs smartphone, flame vs magnet, and y straw.. I win nothing but the scientific literacy I came with, yayy! :D

[@taemien9219]

In the first example I knew the popcorn kernel would not pop. The tinfoil doesn't have the passive gain (and probably has the opposite effect similar to a faraday cage by scattering the signal instead of focusing) required to elevate the signal to the wattage needed to boil the water inside the kernel. Your microwave oven is 1100W on average. The cellphone signal is around 0.1 to 0.2W. They emit the same frequency, but the power output is much less. For example a decent sized satellite dish can increase gain quite a bit, as it needs to in order to push a signal through the atmosphere and reach the satellites in orbit. But the signal going to a dish typically goes through an amplifier before being increased by the antennae itself. Cellphones won't have the output needed. The tinfoil was too small and did not have much of a surface area shape to function as a parabolic reflector.

[@Dexaan]

2/3. I figured there was enough air displacement in #2 to put out the match

[@JokingJames2]

Maybe it's just because this is meant to be more for kids but those first 3 videos to me were the equivalent of like: 1 - If you build a simple machine, it works! 2 - If you hold your hands together and concentrate really hard and say "kamehameha" with all your heart, you can shoot a beam! 3 - If you apply heat to cotton, it combusts! Now which one was fake?

[@joewell6435]

Unnecessary inventions should make a 2 person straw

[@JackieBright]

All you need is to add a one way check valve to each person's side of the straw. You could theoretically add as many people as you wanted if you had perfect pipe and fittings

[@Kalvinjj]

@@JackieBright OR everyone cooperates, then it works without valves!

[@JohnSmith-ty2he]

@@JackieBright Was exactly what I was going to say lol.

[@TheLobsterCopter5000]

But if two people are sucking on each end of the straw simultaneously won't it still work because the air pressure is dropped in both exit holes?

Initially i thought thats what he meant and that it is Not the Fake. But then the Video Just showed one Person. It would be interesting to See two people using the Split straw.

[@randomnpc445]

That's why he specified "whenever they want" and not that it was simply possible for two people to use it.

[@Leandorz]

I knew that the one with the irregular plastic thing was true because when I was younger I went to a summer colony for kids and when we would eat I remember spinning the knife on the table, and on one side it would spin fine and on the other it would like kinda vibrate and turn around.
