The GraviTrax Action Set Energy gives marble runs the power and energy they need to roll balls up and down dynamically! With the diverse GraviTrax elements from the Energy Action set, balls can run through different levels in the track and keep gaining speed. Use the Light element from the POWER line to build upwards and give your balls new energy with the Vertical Cannon. There are no limits to creativity and fun—for builders who want a tricky ball track experience full of variations!
