Kinetic Sand: 98% Sand, 2% Silly Putty Ingredients

September 23, 2013


This is a video demonstration of Kinetic Sand, a sand play toy made from 98% sand, and 2% Polydimethyl siloxane, a "silicon-based organic polymer...particularly known for its unusual rheological (or flow) properties." It makes the sand act...weird. Also, at $45 for 5kg (~11 pounds) of Kinetic Sand, it sounds like either polydimethyl siloxane is really, really expensive, or somebody's price gouging. Just saying, I'll sell you a bag of cat litter mixed with paint thinner for $10. It might not act the same, but neither will your kids after they eat a handful.

C OINTINEU FOR HTE VIDEO (I'm typing with my elbows).

Thanks to Roland, who may or may not be a headless Thompson gunner. In my mind he is though.

    This is totally messing with my cat's head. Kinetic litter box was a successful troll.

    But, does it blend?

    So basically you wad or cut or mold it into vague shapes and it crumble apart at the slightest touch? Over and over again? Sounds fascinating.

  • It's interesting that the ad only ever shows adults playing with it. Which is fitting cuz right now I'm thinking, where was this when I was in college? I was following the Grateful Dead in college, if that gives you an idea.

  • Billie Hutcherson

    My grand daughter who is 4 played with it for hours she loves it I wish u could buy it in biger pks

    Cheap man version: Cornstarch and water!

    He forgot about SQUAND!

  • Laura

    I was just thinking that. Isn't that just Squand? I had purple Squand!

  • Jeffery Dodds

    Warning: if Kinectic Sand touches old-fashion sand then old-fashion sand becomes Kinetic Sand. What could go wrong? <cough>Ice-9</cough>

  • Awesome reference.

  • Benjamin Cody Collins

    Why does it matter that it is gluten free ??? Are we feeding this stuff to the kids or letting them play with it ???

  • Stephen Ingrum

    DO YOU know how many people die every year from gluton???? oh, zero, that's right- it's just this year's carb.
