Launch more marbles! With the spinner up to six balls can be started at once. Watch as the marbles are sent on a race through your tracks. This extension allows you to build up to six different track courses. Combined with the Starter-Set, you could have up to nine different tracks launched at once. How many marbles will you race? This STEM system [Science, Technology, Engineering and Maths] is an ideal one to teach kids about gravity, magnetism, kinetic energy and fun.
