Do You Want To Build A STEM Snowman? Recipe: What you need: 2 cups baking soda 1 teaspoon Dish Soap (like Dawn liquid dish soap) 2 Tablespoons of salt 8 Tablespoons of water A big dish, pan, or other container to contain the mess (I like using a big plastic lid I saved that came from one of those disposable turkey baking pans) A couple of cups of vinegar (I used distilled white vinegar) Add-ons to make your snowman’s fabulous features (carrot nose, chocolate chip eyes, etc.) : ) What to do: In your waterproof container, combine the baking soda and salt and mix well. Add in the soap; thoroughly combining the ingredients with your hands until it becomes a crumbly dough-like substance. Add the water. The dough is ready if it can be formed into a ball, but if it is still to dry add 1 Tablespoon of water at a time until it can hold the form of a ball. Make your snowman and decorate him. Now you are ready for some foaming, snowman “melting” action! Put vinegar into a squirt bottle, or other squirting device and squirt away at the snowman. It works best if you add lots of vinegar at once to create the biggest reaction
