ABSTRACT:
The invention is a propulsion process for lightweight miniature toy boats which comprises the interaction of certain organic compounds containing certain chemical radicals with water in such manner as to temporarily increase the surface tension of water in the vicinity of application to said boats resulting in a propulsion force to propel said boats with sufficient speed and sustained activity as to constitute a novel and interesting toy for young children.
