As you can probably guess by the name, this toy is constructed using strong bamboos. Multiple holes are drilled in the bamboo splits and a flexible stick is then snaked through these holes. The end result of this is that the splits take the shape of an A. You will also need an elastic band. Attach the elastic band to the bottom of the structure you made and the other end to a small stick of wood. When using the boat, just turn the rubber band and let go of it. As you can imagine, the rubber band will unwind, forcing the stick to spin which propels the boat front. Children make use of them during the monsoon season and you can see them playing with the bamboo boats in puddles that occur during the rains.
