Thingiverse user Ben of Camas, WA, designed and printed this sleek rocket, filled it with baking soda and vinegar, shook it, then placed it on the ground and watched it take off.
True success! Today, powered by pure bicarb ($1.99) and 5% strength pickling vinegar ($0.99) it flew as high as the house – about 30 foot! Unfortunately, the wind blew it onto the roof and it’s now in the gutter. This design works though!

I’m impressed that the printed shape will hold the pressure of the expanding gasses.
