Model Rocket Engine In A Vacuum Chamber – Will It Burn? 4K Slow Motion


I Ignited a Model Rocket Engine inside a giant vacuum chamber i build to see whether or not it will burn while filming it in 4k slow motion. the idea here is to replicate how rocket engines and Rocket motors burn in space in a vacuum where there is no air.

There are many Skeptics out there who think they’re rocket engines cannot burn in space at all, in a way we are busting a myth, but this was a viewer request.The result of this burning in a vacuum chamber was very fascinating, surprising and interesting.

In space, rockets zoom around with no air to push against. What’s going on?Rockets and engines in space behave according to Isaac Newton’s third law of motion: Every action produces an equal and opposite reaction.When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.


The rocket ejects a mass of burned fuel to produce a force. The force produced is proportional to the amount the mass of the combustion products (the exhaust) was accelerated. This follows from F=ma (Force = mass x acceleration)So, the more you accelerate the exhaust, the more force is applied to the rocket.
