And i have some better idea to enhance power of the engines in videos. I think if you make size of holes more smaller the engine will be much more powerful than now.

The more I think about it, the more I realize how much time and effort was put into this video.

If you reduce the open space for the propeller, you will get a better propulsion, because the reaction created by the temperature, in a small open space, will be more concentrated.

Well, now we know what powers the Batmobile 80 gazillion matches Seriously though I’m beyond impressed that you had the skills to build all this stuff.

The results were just jaw dropping.imagine you could make it more powerful by condensing the force of the fire out of a cone shape, it would prevent the majority of the match tips from flying out of the back and control the blast a little better.
