Build your own working skate park model made of real wood! The Mini Skate Park features lots of fun physics action, including a stair descent, rail slide and a jump - so once you build your skate park, you can run marbles through it! The assembly instructions feature a graphic novel with the Tinkineer cast of characters - Kelvin, Joule, Newt and friends - to communicate meaningful STEM concepts in an engaging format. It's a fun way to learn about projectile motion and centripetal force while making an awesome kinetic sculpture! The Mini Skate Park takes approximately one to two hours to build, and measures 6" when finished. Household white glue (not included) required for building.
