How to make a mini sailboat for a school project?

1. Cut the bottle in half lengthways. Use the hot glue to seal the lid on tightly (cut around the lid so one half of the bottle has the lid remaining. Use the popsicle sticks to create a mast and two spans sticking out from the bottom going fowards and back to keep it balanced. Cut a perfect triangle that fits your mast and span from the plastic bag. Make sure it is tight (and I mean tight!) before you glue it down. Ensure you make two layers incase one breaks. Now you need to make a stabilizier, so by gluing three popsicle sticks in a fan like fashion (all touching), , make a small slit in the base of your boat and wedge the fan like thing in with the point going downwards. Now use hot glue to seal up the slit so it is water-tight. There you go!!

For the best answers, search on this site https://shorturl.im/axXv3 Look up past issues of wooden boat to see designs. There are kits you can order. Some of them take much work , you get the wood and plans only. Since there were ferrocement boats that worked, you could make one out of sculpy. Be sure to weight the keel. Paper boats do float. They have a cardboard boat race in many areas in the spring. It just takes the proper shape, and sealing material.

Go to the nearest Boy Scout shop, and ask for a Raingutter Regatta boat kit, they are about $3, and float/sail properly
