With Eureka Crate, makers ages 12-100 will invent something awesome every month. Be it an Articulated Desk Lamp, a Laser Speaker or a fully functioning Wooden Ukulele, your innovator will be putting their creative problem solving skills to work and building projects that bring science and engineering to life. Does Eureka Crate require parental supervision? As part of our design process (we spend 1000+ hours designing each crate), we make sure to test the experiences with kids across the listed age ranges. Projects are intended to be completed independently, but kids on the younger-end of the age range may need more grown-up assistance. Plus, many families enjoy making, building, and playing together.
