The Dolphin Jumper

Yes, of course it flips.

This silly little dolphin gets wound up by your classic spring and gearbox mechanism. It then gets aimed towards a ramp, and once the tail hits the ground as the dolphin ascends the ramp, the pre-loaded spring shoots the dolphin forward through the hoop, doing a flip, and landing on the downramp.

• This product is based on the principles of gravity and newtons laws, as well as rotational inertia.
• Feasibility is an issue with the Dolphin Jumper as not only does it contain unsafe small parts, but it also contains small pieces of constantly stressed plastic, which will become brittle and snap over time. Manufacturing is cheap however, since it consists solely of plastic molds and springs.
