This super neat water toy helps demonstrate the laws of physics involving pressure and buoyancy. Fill a clear, smooth-surface plastic bottle with water and place the little jellyfish inside. With the lid tightly fastened, gently squeeze the sides of the bottle to watch the jellyfish sink. Release your grip to let the jellyfish rise again. Experiment with these techniques to discover which tricks the jellyfish can do. The jellyfish has a body of approximately .75” x 1” and 1” long tentacles. ~ Brianna
The Magical Jellyfish performs amazing hydro dynamic tricks! First, place the jellyfish in a bottle of clean water. Then, squeeze and watch as jellyfish spins and floats up and down. Assorted colors: Blue, Red or White chosen at random.
Kids will learn about pressure and density, along with buoyancy and Archimedes’ principle.
