How is the Contraptions Reactions set different from standard KEVA planks?

Beyond 178 wooden planks, you get reaction pieces—bells, dowels, a bowling pin, string, balls, and more—to trigger chain-reaction events.

What will my child learn?

Hands-on lessons in balance, leverage, geometry, force and motion while they experiment with cause-and-effect.

Do the planks require glue?

No, precision-cut wood stacks perfectly—kids can redesign contraptions endlessly.

Suggested for ages 7 +—challenging enough for tweens but still safe and open-ended.

Does it come with build ideas?

Yes, a 16-page illustrated idea book jump-starts creative marble-run and chain-reaction challenges.
