Glow-in-the-Dark Scuba Diver, Green

Fancy some colorful diving fun? The glow-in-the-dark jellyfish-shaped scuba diver gives children exciting sights in the water! Simply place the plastic jellyfish in a filled water bottle, press the bottle and the little scuba diver moves through the water.

The special thing about it: Thanks to the glow-in-the-dark effect, the jellyfish glows in the dark and its movements look even cooler. But why does the jellyfish dive or submerge? The included child-friendly explanations (German language) teach you that the jellyfish is filled with air and floats up or down because the density of the air bubble changes when pressure is applied to the bottle. Science to observe and try out, making the Scuba Diver Jellyfish a great souvenir!
