In this super fun, easy, and inexpensive tutorial, we're going to make an edible excavation that the young Excavating Adventurers in your life will love. This Gummy Worm Discovery Dig tweaks the good old fashioned Rice Krispies Treats recipe by adding a fun Excavating Adventures spin. We’ll take this tasty treat and turn it into a delicious layer of topsoil to explore and discover the yummy gummy worms we have hidden inside.


Fun Fact: Become a soil scientist for the day on your Gummy Worm Discovery Dig. A soil scientist studies the upper few meters of the Earth's crust in terms of its physical and chemical properties, as well as its biological components, such earthworms and other creepy crawly creatures.


Excavating Adventures Pro Tip: Buy a pack of chocolate rocks and add them into your Gummy Worm Discovery Dig. Not only are these little candies yummy, but young Excavating Adventurers will love the extra items to discover.
