Turn cardboard into moving machines with this hands-on kit.

Take your upcycled creations beyond static structures with these specialized motion-building components. Fun for ages 5+. Made to be used with the DIY Discover Kit (sold separately) the DIY Kinetic Expansion Kit is designed to add life and movement to cardboard construction, these accessories turn static boxes into interactive machines, vehicles, and creatures. By introducing rotation and pivoting to your builds, these tools help makers explore basic engineering and mechanics through hands-on, low-tech play. Each kit is sold separately.

Features of the DIY Kinetic Kits include:

• Crafted from reinforced, high-strength nylon to withstand the weight of large-scale builds like forts and vehicles.
• Eliminate the mess: These parts fit seamlessly and don't need any messy glue or tape.
• Encourages an understanding of physics and mechanical movement through trial-and-error making.

The Spin Hinge Kit is the ultimate multi-axis connector for moving parts. Whether you need a door that swings, a wing that flaps, or a joint that rotates, this versatile component makes it happen.

• Acts as both a pivot and a hinge, allowing for smooth rotation or traditional swinging motion.
• Includes a 360° rotating base and a 180° pivoting hinge, allowing for complex movements like shoulder joints or adjustable mirrors.
• The included tensioned pivot is engineered to hold its angle under light loads—perfect for keeping a "trunk" open or a "crane arm" at a specific height.
• Use it to create moving jawbones on creatures, functional hatches on forts, or adjustable solar panels on space stations.
• Fully compatible with the standard Scru and Scru XL for secure, tool-free attachment to any cardboard thickness.

Bring high-speed action to your builds with the Roto Ring Kit, a dedicated rotation hub designed for circular motion. This is the essential part for any project that needs to spin, roll, or whirl.
