Water Glitter Bag
Take a sturdy Ziploc and fill it about three-quarters full with water. Add glitter, foil confetti, or small interesting bits and pieces. Carefully squeeze out excess air and zip the bag. You can seal the bag more securely by reinforcing it with packing tape. Show your toddler how to shake the bag and create interesting effects, such as holding it up to the sun or a lamp to see how the glitter catches the light.
