You'll need: a glass jar with a tight-fitting lid; a plastic figurine; waterproof glue; distilled water (you can also use boiled and cooled tap water); liquid glycerin (available at crafts stores); glitter.
Let your child pick out the figure, then glue it inside the lid and let the glue dry. Fill the jar with water, a squirt of glycerin (it helps the glitter swirl), and the glitter. Screw on the lid tightly, then flip!
