Balloon Powered Benchy Boat

This is a cool model that glides on a smooth surface when you fill the balloon up. Soon, I will have a version that is powered by 2 balloons

The way to fill up the balloon:

1. Attach the balloon
2. Blow into the hole on the bottom
3. When getting your breath back, pinch the balloon so it holds the air in
4. Repeat steps 2 and 3 until you think the balloon is big enough
