Concept III. One Person See-Saw

• This toy is based on a simple machine, with a fulcrum. It takes an input of force and builds up potential energy when the force (the child) is moved down. This energy is released to bring the toy back up.
• 
• When a wants to ride the one person see saw, they place the included pin in the weight rack (similar to a fitness machine), as shown in the top picture. they then get on the see saw and use normally
• When the child jumps to start the see-saw, the weight is lowered and the spring is tightened. when the spring is tight enough (depends on weight entered by child into rack), the child is brought back down
• This would be quite expensive to build, but would require nearly zero maintenance. The toy would be very durable, since it is made of steel within the casing, and there are not many wearable parts, if used correctly
