In this fun and easy activity for kids, we’re going to use a simple recipe to make super cool sand slime and go on a sensory search to discovery seashells.
  • Sand (You can use colored sand to make your slime even more unique!)
  • Clear glue
  • Liquid starch
  • Water
  • Bowl
  • Measuring spoon
  • Measuring cups
  • Craft stick
  • Optional - lotion (Using liquid starch as the activator to make slime can often cause the slime to be sticky. Rub a little lotion into your hands and the slime will not stick.)
  • Assorted small and medium sized seashells. You could also use small plastic ocean animals.
