Marble Roller Coaster
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?
Why it’s awesome
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.

Additional details
From the desk of the product designer:
Behind the design
“The downward slope leading up to the loop in the Loop-the-Loop build was inspired by the Brachistochrone Curve – meaning that the marble picks up more speed faster to complete the loop and continue on the track!”

Super duper favorite! The instructions were clear enough that we used the book and not the videos.

My son has been playing with this for hours! He's having a blast changing the setup and seeing how fast it can go. So happy we purchased this one.
