Just add water and watch as the crystals expand to create tactile fun for your students!
Sprinkle one teaspoon of Brain Freeze crystals on a tray. Add approximately 12 ounces of water. The Brain Freeze turns to gel for ooey, gooey fun. Kids enjoy "writing" letters or words with their fingers. Multisensory reinforcement helps cement concepts into students' brains.
Each bag contains enough Brain Freeze for more than a dozen trays (Brain Freeze can be dried and reconstituted with water). Easy clean up -- simply let Brain Freeze dry and store for future use. If gel spills, wait until it dries and vacuum crystals.
Tactile trays sold separately.
