Who can you trust to guard your precious coins? Your loyal coin-eating dragon, that’s who! It turns out, the world’s coolest piggy bank is actually a dragon bank! Make your very own mechanical dragon and turn your spare change into savory savings. 

With the Gecko Run: Snake Expansion Pack, you can send your marbles through a maze of sharp curves and see how it affects their speed. But watch out: only if you place the snake correctly in your marble run will the marbles make it through!  

With the Gecko Run: Twister Expansion Pack, you can give your marbles a real spin. This not only brings extra fun to your Gecko Run marble run, but also makes the laws of physics visible.

Get hopping with the Gecko Run: Trampoline Expansion Pack! Can you position the trampoline so that the marble flies really far? Can you even bounce it downward, or catapult it up to a higher track?

This timeless scientific instrument has been reimagined in a fresh, new design. Experiment with the gyroscope to learn about the physics of motion, forces, and gravity.
