      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.

      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

    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. Just be pressing and holding the two metal parts against each other, causes them to weld after some time, in absence of oxygen.

    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. I think a lot of people don't realize that gas has mass.

      You saw it not move because of the gas expelling. The gas had to use the resistance of the wall of the vacuum chamber before it could have a reaction and propell.

    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.

      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.

Place a scale under the vacuum chamber... the rocket should cause a positive change to the scale equal the thrust of the rocket.
    Then, place the lid of the vacuum chamber on but don't evacuate the air and repeat the experiment. Does the scale measure a change?

      @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.

    I can help anyone understand how rockets work, but only if they answer some questions.
    I find no amount of trying to force someone to understand will help them.
    They must see the answer, themselves.
    If they answer a few questions, they will figure out how it works.
    Let's think about a rocket engine running right here on earth in an atmosphere before thinking about "in a vacuum".
    So, imagine a single Space Shuttle Main Engine (SSME) igniting right here at sea level.
    These consume about 500 kilograms of liquid oxygen and liquid hydrogen per second and expel the "exhaust gas" at about Mach Eight.
    1 - Does the "exhaust gas" have any mass?
    2 - Did the rocket engine "accelerate" this exhaust gas?
    3 - Can mass be accelerated by anything other than a "Force"?
    Answer these three questions and I will get to the ones that are relevant to "propulsion in a vacuum".
    But they must demonstrate that they understand these basic physics terms.

      ​@@papalegba6796 Dictionary definition of vacuum:

      b) a space partially exhausted by artificial means (such as an air pump)
      c) a degree of rarefaction below atmospheric pressure
      What is rarefaction you ask? This should explain it to you: "A natural example of rarefaction occurs in the layers of Earth's atmosphere. Because the atmosphere has mass, most atmospheric matter is nearer to the Earth due to the Earth's gravitation. Therefore, air at higher layers of the atmosphere is less dense, or rarefied, relative to air at lower layers."

    Science can be wrong sometimes, even with "vacuum" in this chamber there is still air and other medium left that can be used as mass for the rocket to travel through. In a perfect vacuum such as in space, these mediums do not exist. And the rocket is way too big for this chamber, it used the "wall" of the chamber to gain its momentum.
    The question remains, can a rocket gain momentum in a perfect massless medium completely independently without a reference point to launch from?

Used from the late 1800s through the 1940s, nitrate film was incredibly flammable and caused some major fires in movies theaters."

    Set off a blank round and show that explosions _do in fact_ make sound in space.
    This is a long standing myth I have heard repeated by many experts, even astronauts like Chris Hatfield.
    _Impacts_ don't make sound in a vacuum, since there's nothing to carry the vibrations. but deflagrations and explosions do, as they make their own pressure wave that carries the sound. I can show this myself, but I don't have the voice to reach people like you.
    Please note: a blank will have a hard time being heard in a vacuum, because it doesn't build pressure without a barrel and bullet, so I suggest using a blank larger than a .22 blank, but please also be careful; without air, there's no attenuation of the sound, and smaller pieces of shrapnel hold velocity without air slowing them down.
    Please do this! It's very important the world realizes this. It makes me so sad when I see people shooting guns in space in movies and people thinking them being silent is realistic.
