Title: Toys and games using super-hydrophobic surfaces
Claims: I claim: 1. A toy or game device comprising: A a dry playing board having an exposed planar face layer formed by hydrophobic material that repels water; and B a play element set in motion by a player to slide on the face layer of said board, said play element having an underface formed by hydrophilic material having an affinity for water, said underface being planar and being wettable by water which is repelled by said planar face layer to create a minute air film between the face layer and the play element whereby said element effectively floats on said dry board with virtually no slide resistance. 2. A device as set forth in claim 1, wherein said board is a track and said element is in simulated vehicular form adapted to slide on said track. 3. A device as set forth in claim 2, wherein said track is inclined to provide a gravity slide. 4. A device as set forth in claim 2, further including means to shoot said element to slide at high speed along said track. 5. A device as set forth in claim 1, wherein said element is in arrow form and slides with respect to different symbols printed on said board whereby when said arrow is at rest it indicates a particular symbol. 6. A device as set forth in claim 1, wherein said face layer is super-hydrophobic. 7. A device as set forth in claim 6, wherein said super-hydrophobic face layer includes fumed silicon dioxide.
