A small boat that you wind up and will go forward in a pond or swimming pool
A list of things needed:
1. A square peice of wood
2. A thin square peice of wood
3. A thin rubberband
4. A saw
Step 1: The Main Part of the Boat
First you will need a peice of wood (preferably a square peice).
Cut it so it is an arrow shape. Then cut a box out of the bottom.
It helps if you make round cuts on either side of the box so the water is pushed in a more water dynamic way.
