Ingredients

  • Wet Baking Soda
  • Small Treasure / Gold Coins

  • Fizzy Tub Colors / Food Coloring / Water Color
  • Squeezy Bottles
  • Container
  • Water Table Optional

Instructions

  • 1. To create treasure rocks, simply take large handfuls of wet baking soda from another activity. If you don't have any leftovers, just add a little water to unused baking soda or simply do another activity first.
  • 2. Place a gold coin or treasure in the middle and form the baking soda around it. Repeat until you have several treasure rocks for the activity.
  • 3. Let the fizzy treasure rocks dry for several days. Try to avoid handling them as much as possible, as they can be quite fragile once they're dry.
  • 4. Once dried, scatter the treasure rocks in the water table. You can also put some extra dried-out baking soda that you hadn't turned into treasure rocks.
  • 5. For St. Patrick's Day theme, you can color your vinegar green and yellow.
  • 6. Now it's time to let the kids play and decide how to dig up those treasures!
