This is a rocket that can be loaded with baking soda and vinegar.

The rocket and base can be printed in either hard plastic or TPU, but the main idea is using hard plastic.

Then the file “rocket mount” should be printed in TPU so you will get a tight fit between rocket and base (see picture).

The way you use the rocket is to: (the use of the rocket is at own risk!)

1. Go outside, not intended to use in the house!
2. Load the rocket with vinegar
3. Load the base with baking soda
4. Attach the rocket to the base, shake and wait.
