Action & Reaction is a set of construction toys for creating crazy marbles courses, a complete kit for your child – through trial and error, and increasingly precise attempts – to experiment with the main concepts of mechanical physics, such as motion, velocity or the effect caused by two objects colliding... in other words, the principle of action and reaction!

  • A scientific toy for exploring the fantastic world of contraptions and chain reactions, a product designed for children but equally intriguing to adults...for fun-filled moments for the entire family!
  • The Action & Reaction sets are compatible with all the other products from the range: collect them all to create an endless number of circuits and tracks with loads of accessories!
  • The modular components also allow kids to expand their circuits with household objects, which can be added to create mixed, original tracks with growing levels of complexity.
  • The entire range is fully made in Italy.
