Abstract
Abstract A toy, game or other play device wherein a trackway, slide, maze or other play surface is coated with super-hydrophobic material that is highly water repellent, whereby a drop of water applied thereto forms into a ball that can then be manipulated by a player to carry out predetermined play activities. Alternatively, a tiny vehicle or other toy body having a hydrophilic coating thereon may be wetted with water and placed on the super-hydrophobic surface whereby the slightest force applied thereto causes the body to skim at high speed over the surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A toy or game device comprising a playing board formed by a substrate having a face layer thereon formed by super-hydrophobic material having virtually no force of adhesion with respect to water whereby a drop of water supported thereon assumes a substantially spherical form, and a material consisting essentially of water on said layer to create a substantially spherical body movable on said board, said board being a maze having channels forming a circuitous path which is traversed by said body.
Claim 2
Dependent Claim
