We’ve built KiwiCo out of a belief in the importance of developing creative confidence. This confidence helps kids think big and act like creators and producers instead of just consumers. Kids with creative confidence don’t assume one "right way" to build with blocks, paint a picture, or solve a problem. Their unique way is the right way!

By celebrating kids' natural creativity and curiosity, we help parents bring enriching experiences to their children. Children should learn and understand engineering through real world concepts - and have fun doing it!

The Best Starter Kit for Young Engineers (Ages 5+)

Our Kiwi Crate Mechanics Pack delivers three kits for the mechanically-minded young tinkerer. Kids will receive all the materials and instructions to build a mechanical sweeper, disk launcher, and hydraulic system. All three projects encourage creative thinking and problem-solving while teaching children about how similar objects are engineered in the natural world.
