Using the incredibly open-ended Action & Reaction ball-run building system, young physicists get to explore the effects different drops, loops, and turns have on speed and momentum as they send two balls racing against each other.
Snap together the 130 building pieces to create two tracks that are intertwined in all kinds of chaotic ways, from over-and-under zig-zags to a loop-de-loop to a wild spiral tower. Then, use the double launcher to send both balls racing at the same time.
Which ball will make it to the end first? Did it match your hypothesis?
With an illustrated manual to help you get started and imagine new ways to explore, the Action & Reaction Speed Race is a thrilling introduction, not just to the play of physics, but the SCIENCE of physics!
