Generally, we throw away the empty plastic bottles or have a kick practice session on the road. But, you know, you can construct a motor powered Catamaran out of them. The Bottle Catamaran needs only two empty 1.5 liters plastic bottles and Iwoot provides the rest of the kit. To build bottle catamaran, you just need to put the frame together, clasp the propeller up to the motor, add 2 x AAA batteries and fix them in the bottles.
