Construct your own working roller coaster model made of real wood! The Dragon Coaster is full of dips and turns with some engineering and physics thrown in - so once you build your coaster, your 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 roller coaster design and conservation of energy while making an awesome kinetic sculpture! The Dragon Coaster takes approximately three to five hours to build, and measures 8 inches when finished. It also connects with the Skate Park (sold separately), so you can expand your marble empire and shuttle marbles back and forth! Household white glue (not included) required for building.
