Inertial propulsion 2

My first attempt to inertial propulsion short film. It's working, however the base principle in this case is something else than I was expecting. I will improve this device in the future.

A simple impulse reaction propulsion experiment confirming that H. Bull impulse drive is working properly (experiment conducted by JLN Laboratory) There is shown that entire experiment was conducted in ideal horizontal plane. The displacement is about 5 mm long. The reaction masses are expanding in the opposite direction after burning a nylon wire because the spring expansion which is giving the masses required velocity.
