What You Need:

  • One box cornstarch
  • One large mixing bowl
  • Bottle or pitcher of water
  • Spoon
  • Gallon size zip-top bag
  • Small toy dinosaur, person, or animal

What You Do:

  1. Mix ¼ of the box of cornstarch with ½ a cup of water. Stir together, or mix with bare hands.
  2. Add cornstarch and water a few spoonfuls at a time until your mixture reaches the consistency of honey. The end result may contain the whole box of cornstarch and one to two cups of water.
  3. Have your child dip his hands in the newly created ‘quicksand.’ Ask him to move his hands around slowly, then quickly. Some questions to ask here: “How does it feel to move your hands fast and slow?” and “Is it harder to move your hands quickly?”
  4. Now it’s time to get ‘trapped’ in quicksand! Have your child dip her whole hand into the quicksand and then try to pull it out.
  5. Lastly, your child can take a small toy and place it on the quicksand. Let it sink momentarily, then try to pull it out. Discuss how this feels in comparison with pulling your hand out of the mixture.
