PRODUCT INFORMATION

Realistic growing swell polymer brain will grow almost as big as your brain. Just add water and watch it grow!

  • Soak your brain in a large container of water. It can take a few weeks to get to full size
  • Change the water in your container every few days. A polymer hydro-gel may occur on your brain as it grows and should be rinsed off occasionally
  • Your brain will shrink over time when out of water. Your brain may keep growing and take over the world. 

Fun for ages 8 and up
