H2bOater

The H2bOater is meant as a bath-time toy. It is to be filled with a provided chemical, which, when in contact with water, would react slowly and safely, propelling the boat around in the bath.
Chemical reactions is the basis and idea behind this toy.
As this is a bath toy, it can be expected to not encounter very high falls onto a hard surface, so the plastic can be made from a mold, and be made of very cheap and relativly strong plastic.
