Our Mission
We engineer sensory sand that sticks to itself—not your floor. Using clean, biodegradable binders and lab-grade testing, we deliver the tactile joy kids love with the cleanup peace parents need.
Our story
Founded by a materials scientist dadFrom Garage Idea to Cult Favorite
It started with a sandbox, a spreadsheet, and too much curiosity. Every weekend a new ratio. Every batch closer to 'the feeling.' Now we bag that feeling for your playroom.
The Mad Dad Origin
As a materials scientist and parent, I was tired of the greasy residue and endless cleanup from conventional kinetic sand. I knew there had to be a better way—a formula that delivered that perfect tactile satisfaction without the mess. Three years, 127 iterations, and countless playground tests later, we cracked it. Our biodegradable binder system creates the ideal texture while keeping grains together for easy cleanup.
Lab-Grade Process
Every batch undergoes rigorous testing for texture, safety, and performance. We measure grain size distribution, binder cohesion, and cleanup efficiency in our home lab before it reaches your family. We're transparent about our ingredients and testing because we believe parents deserve to know exactly what their children are playing with.
