The Catamaran boat is a fun craft for older grade school children to make for a number of themes including: Columbus Day, learning about Japan, Transportation, Oceans and Bouyancy. Yes, the boat will really float, but as the paper gets saturated with water, it will sink and be ruined. This can actually start a neat discussion about what made the boat float to begin with and then what made it sink. This boat is the coolest boat ever, it is quite hard to fold so you need to to have patience but it worth the trouble because the result will be a awesome boat.
