Become a thrill engineer and build twisty, turny tabletop roller coasters. Start with a battery-powered Ferris wheel that lifts marbles to the top, then add tracks and towers to make a figure eight or loop-the-loop track. Switch it on and watch the marbles zoom round and round. Ready to build a rad ride of your own?

Engineer thrills

Build towers and tracks to make marbles roll ‘round and ‘round.

Marble-ous motion

The Ferris wheel turns the coaster into a loop that never stops.
