This Halloween activity lets kids explore melting and freezing with a gross-out green brain. Use warm water and salt to make the ice brain dissolve, and squirt saltwater from syringes for extra gooey action. It's a spooky, hands-on science play that's simple to set up.

Directions

  1. Collect a brain-shaped mold, green food coloring, novelty syringes, salt, a tray, and an old towel.
  2. Fill the mold with water and mix in a few drops of green food coloring.
  3. Put the mold in the freezer and leave it for three days until the water is completely frozen.
  4. Prepare a bowl of warm water, have salt ready, then remove the ice brain from the mold and place it on a tray.
  5. Pour or squirt warm water over the ice brain to start melting it.
  6. Sprinkle salt onto the ice to accelerate the melting process.
  7. Optionally, dissolve salt in warm water, draw it into the syringes, and spray the solution onto the brain.
