We make toys that use chain reaction machines to teach critical STEAM skills to kids 7 and up.  




Freshly funded! Check it out:


How does it work?

Kids build with Momentix pieces...

...and combine them with things they already have...

...to create chain reaction machines!

Our Challenge Cards give them a place to start

Our Idea Booklet gives them the tools to get un-stuck while learning basic physics and design concepts

Our next toy is in the works.

Be the first to know the details! 

Momentix was created by two recent physics grads. We noticed a discrepancy between the skills scientists and engineers really need and the ones we were taught to value.


The result was Momentix— a toy with built-in opportunities to practice creativity, resilience, and problem-solving.
