Roller Coaster Science

Discover how science makes the world go round — with this roller coaster–themed crate! Build your very own loop-the-loop coaster, send a metal ball on a twisty ride, and learn how the centrifugal effect keeps the ball from falling off. Design a snazzy sign for your coaster with color-changing markers. Then build another classic amusement park ride, a centrifugal effect–powered spin-o-tron!
