Instructions:
- Add about ½ cup of cornstarch to the mixing bowl.
- Begin adding the tonic water one tablespoon at a time. You want to keep doing so as long as your oobleck remains fluffy. If you think the oobleck is about to get soupy, cease adding tonic water. If you do end up adding too much tonic water, just add a little more cornstarch to balance out the mixture.
- Push the excavation items into the oobleck.
- Whenever you move your hand through the cornstarch and water mixture gradually, it’s going to feel like slimy liquid. If you tap hard on the mixture, it will behave like a solid.
- Search for a dimly lit or darkened room. Once inside the darkened space, hold a black light above the container of cornstarch and tonic water. You will observe the oobleck glowing blue. Continue to examine the amazing glowing oobleck and enjoy allowing your little one to explore and excavate the items.
- Optional - Add a few squirts of washable glow in the dark paint to the oobleck for an extra layer of glowing fun!
