Build a functional jet engine out of empty beer cans and an old hair dryer. Minimal tools required.
I had always wanted to make a jet engine, then, one day i realised i had the parts available to do it. So, I did!
It was made out of STEEL beer cans, copper hydraulics tubing and an old hair dryer.
It produced measurable thrust which was only briefly tested on a rig that utilised model train tracks and 4 boggies.
More information is on my website at: https://letsbuildone.wordpress.com/jet-engine/
I have a video of various tests in the development process and it in action on my website and below:
I Appologise for the poor quality pictures that were taken on my old phone. Unfortunately the engine has been ravaged for parts by my brother, so i can't take new photos.
