Learn all about buoyancy!
A simple and fun experiment, the Jellyfish Diver will provide hours of joy. Simply get a plastic bottle, fill with water, pop in your jellyfish, and seal with the lid. Once complete, gently squeeze the bottle and watch as the jellyfish sinks. If you want the jellyfish to float back up, simply release your hold on the bottle. Jellyfish Diver colours will vary.
Not suitable for children aged three and under.
