Balloon Powered Boat
By no means original, this was a really simple design I had to build. The hull is cut with a bandsaw at 15 degrees, 1/2” dowel with a 3/16” hole in the middle. Glued and bisected by another 3/16” hole out the stern. A balloon is filled up and dropped onto the stack then released in a bathtub. Finished with hemp oil.
Kid test to follow.
