Coil Launcher

I sprinted across the wood chips right toward a bright red rocket mounted on a giant iron spring! Leaping onto the footrest, I grabbed the steel handles with both plush hands and pumped my legs hard. Boing-sproing! The heavy spiral beneath me compressed and launched backward, rocking wildly back and forth. The whole park swayed past my visor in a dizzy rush of sky and trees while the thick iron coil hummed with stored power under my feet. Maximum thrusters engaged! #AstroBot
