Uberstix Sailboat--Science Project Series--Full-fledged fun sails ahead! What you build actually works! Using recycled water bottles, you can build an actual working sailboat. Water Bottles make it float, the wind makes it sail. Set sail to go up wind or down wind. Tack and jibe, it's easy and fun. As part of the Science Project Series, a 3 to 4 hour lab sheet lesson plan is included that teaches the basics of sailing and the function of the keel and rudder. You can also modify your boat to create your own design; single hull, catamarans, trihulls.
