  • Patent number: 9623341
    Abstract: A water teeter-totter system is a teeter totter that uses the inertia developed while in use to operate water pumps to pump water through a plurality of spray nozzles to combine water amusement with the fun of gliding on the device. The downward motion of each side of the teeter totter actuates a different pump to spray water alternately at one user and then at the other user. A centrally located tube is able to be coupled to various ornamentally designed appurtenances that perform an action from spraying water through the appurtenance to blowing up balloons.
