Tustin High School InvenTeam

The Tustin High School InvenTeam invented a device to remove chewing gum from sidewalks and other concrete surfaces. The device incorporates an electric heating element to heat the gum, a biodegradable chemical solvent to loosen the bond between the gum and concrete, and a brass brush to mechanically remove the gum without damaging the concrete. Each piece of gum is removed in 30 seconds. The device has a similar form factor as a household vacuum cleaner and it draws up to 275 amps from an AC wall outlet.

Horizon Science Academy Cleveland High School InvenTeam

The Horizon Science Academy Cleveland High School InvenTeam invented a device to lift a kayak from the ground onto a roof carrier on top of a car. The device is powered by a standard 12 V car outlet which lifts the kayak onto the roof rack in under 30 seconds. The only human power required is to strap the hoist lines onto the kayak which are secured with Velcro. This invention makes it possible for people who cannot lift their kayak to continue participating in an activity they enjoy.
