Crunch it, smoosh it, pop it, and see the science
One of the most satisfying stem toys for kids ages 8 to 13, this hand-crank crushing machine lets kids load up everyday items and slowly smash, squish and crumble them with 30 times their own strength. Three interchangeable crunch plates each crush things differently, so every object becomes a new challenge, and all the mess stays inside the chamber, which rinses clean in the sink. A QR code links to an exclusive how-to-play video that explains the engineering behind powerful crushing machines, and the built-in phone holder is there for filming every slow-motion crunch.
Why you'll love it
- 30x crunching power: Crank the wrench and multiply your strength to crush objects with satisfying force
- 3 crunch plates: Swap plates to crunch, smoosh or pop for different smashing effects
- Mess contained: Everything stays inside the chamber, then washes out in the sink for the next round
- Science you can see: Scan the QR code for the how-to video on the principles behind crushing machines
- Film it, share it: Built-in phone holder for recording the destructive ASMR moments
Perfect for: Christmas gifts, birthdays for ages 8 to 13, rainy-day science, content-making kids
