[@uh-nuh]

good idea, but electronics might overheat or cant resist against the vacuum. He can take care of the cooling by covering a large piece of metal with thin nylon(to prevent possible shorts) and using some cheap thermal paste. (A chunk of metal should be able to handle and store some heat) But I'm not sure about the circuit board. For example, the capacitors on the circuit were not made for low pressure, I am sure they would expand like a balloons Maybe he can make a small pressure-resistant container and put the Tesla coil inside it, then drill separate holes for only the tip of the Tesla coil and the power cables and plug/seal them with silicone, or if he manages to make a pressure-resistant container, he can simply put the batteries directly inside. I'm not sure how he can turn it on and off, maybe Spend more money and get a remote control

[@oleg4966]

I studied to be a chemist, and this vacuum chamber scares me because of what will happen if it ever implodes. Even small vacuum chambers can throw around glass shrapnel at dangerous speeds when they implode - and this monstrocity's explosion will be like a bomb going off: pretty hard to survive if you're in the same room with it. An implosion is unlikely with walls this thick (assuming it's tempered glass), but it could still happen if the walls got hit hard enough by something that is harder than glass.

Maybe you can somehow test the fact that pure metal alloys can be cut and then fused back again in (an inert) space. Oxidation under normal sircumstances due to oxygen in the atmosphere, prevent metals from fusing back again. Apparently in space this works different.

I think it might be cool to try a farnsworth fusor experiment to perform fusion. Fusors tend to be difficult to see because of the bulky vacuum chamber surrounding it. but if you have a large chamber you could show more clearly all of the parts and since the fusor creates a glow you may be able to visualize the operation more clearly. I'm not sure what the vacuum requirements are though. Also requires being able to inject small amounts of deuterium fuel.

[@lesliespeaker668]

This. And do some other plasma experiments also, adding small amounts of different gases, making big objects glow and such.

[@RMX7777]

A demonstration at the voltages and pressures needed for fusion would produce a large number of X-rays. The steel walls of typical fusors attenuate the radiation, keeping the operator safe. A radiation shield would need to be constructed if he would build a working fusor in this chamber. That aside, there is likely too much off-gassing from the plastic of this chamber. The pressure he reached here was 0.02 atmospheres, for fusion you would need around 0.00001 atmospheres.

You should make a contraption that does nothing but mechanically throw mass out the back to produce thrust, as in reality that is all that is needed (like maybe a tiny compressed spring powered cannon type device). If you were floating around in space, you could produce thrust by taking off one of your shoes and throwing it in one direction, you would then have some thrust in the opposite direction.

Something to try: Place your old vacuum chamber into the new big one and activate the big one first, and when it reaches almost vacuum activate the old one and see if it can create additional vacuum inside of it.

It doesn't start moving until long after the smoke hit the wall. likely because the reaction started out too slow to produce enough pressure to move the syringe. Once most of the flash paper caught on fire the exhaust speeds went up exponentially and that's when it started moving

​@Amplified_TruthTHANK YOU. Well said. Hopefully the "scientific community" will leave your comment up and allow opposing conversation. Which is rare these days. My 12 yr old son watched this video last night. Immediately when action lab showed the slow mo of the jet stream hit the side of the box and finally move my son said, "LOOK! IT PUSHED OFF THE SIDE OF THE BOX". Then today we brought up the subject and I told him people in the comment section get mad if ypu say that. And I told him that achilds mind that isn't corrupted with programming can see things better than adults that are programmed what to think. He said, yeah, it's like a story we read in school about the emporers new clothes, which really werent there and the only one that said it was a child.

oh, and i should probably clarify, I'm not a flat earther, or at least not yet(I still have to do a laser test across 50 miles of water, to see 4 myself). . Yet I highly doubt rockets can propell themselves in the vacume of the so called outer space.

Have you ever tried to let a plant do fotosynthesis in martian atmospheric composition conditions (at surface level) ? Ofcourse not the freezing temperature conditions! Just the 98% carbondioxide at martian air pressure. Maybe try to burn a candle with the oxygen produced by the plant. For a nice visual effect!

[@lajoswinkler]

The plant would die. Pressure on Mars is effectively a vacuum. No photosynthesis. Plant desiccates as turgor drops and that's the end of it.

[@col0342]

Photosynthesis requires water (in addition to CO2 and light). Not much of it remains inside the cells at such low pressures.

You should test if sound is heard outside the vacuumchamber and if it cant then how much of a vacuum is needed to get silence, and if you can hear it if it touches the sides, i dont know if it can be done without the item "floating" in the middle somehow, cause i think the noise might be heard if its held up from the bottom or dangeling from the ceiling.

[@lasagnahog7695]

Huh, I never thought about the fact that the vacuum of space setting up a huge pressure difference makes rocket propulsion more efficient. Plus you're not trying to push through more atmosphere. This is why I stick around for these videos despite the simple seeming questions asked. Like, 'do rockets fly in space?' is such a simple question to answer through observing rockets flying through space but, as always, the 'why' is where the interesting stuff happens.

[@TeamYankee2]

You could put a flat earther in there and suck out all the air ?

@@xXthatkushXx Flat Earth or not it's clearly pushing off the wall, it doesn't move at all until the smoke hits the side and curls up. Watch the slow motion, if the experiment worked it would move as soon as the smoke left the syringe, but it doesn't since there is nothing to push off of.

[@xXthatkushXx]

@jimc9581 while it APPEARS to be pushing off the wall, it isn't. It's not going to start moving the instant the exhaust leaves the syringe. It takes a little while for the exhaust to build up enough energy to move the (comparatively massive) weight of the syringe.

Instead of the rocket/syringe, can you please demonstrate that launching a small mass (ball bearing?) still causes force/thrust in the opposite direction when in a vacuum chamber? That would prove it is not pushing off the chamber walls, as some people seem to believe.

Why don't u wear an oxygen mask in the chamber😂

[@thomasdalton1508]

I know you are joking, but in case anyone isn't aware, an oxygen mask doesn't work in a vacuum. Without pressure outside your chest to balance the pressure inside your chest, you can't breathe. There would be no way to exhale against the pressure from the mask. Even if you took the mask off to exhale, I don't think it would really work.

Action and reaction requires only two objects, one acting on the other. The engine accelerates the burnt gases, and they exert a reaction on the engine. There is no need for a third object or entity for this to work. No atmosphere to be "pushed against". It is the gases themselves that are being pushed, and it is the gasses themselves that cause the reaction on the engine and propels it on the other direction. Yes, rockets do work in a vacuum.
