Instead of being powered by electricity or expensive-to-replace batteries, this Solar Rollercoaster is cleverly designed to run on sunshine! It's a brilliant way to introduce kids to clean, free, renewable energy while having plenty of fun at the same time! This Solar Rollercoaster Kit comes flat-packed for build-it-yourself fun; simply push together the sturdy translucent pieces to create a miniature rollercoaster powered by light. Once fully assembled, the rollercoaster's solar panel powers a motorized moving staircase that carries the plastic balls included to the top of the structure and onto the track - each ball then whizzes down the spiral slide of the rollercoaster before starting the cycle from the beginning. So as well as being a great way to learn about renewable energy, you'll never need to pay out for pricey packs of replacement batteries again - bonus! Solar powered toy rollercoaster - 4 purple marbles included. Economical - absolutely no batteries required! The solar panel converts sunlight into the energy needed to power the rollercoaster's motorized moving staircase A great way to demonstrate how light energy can provide clean, free, efficient energy Flat-packed for build-it-yourself fun Recommended for ages 10 and up A fun but educational gift Full instructions included.
