Learn about pressure and buoyancy with this clever little Jellyfish Diver!
It’s a fun, educational and hands-on science experiment for the engineering and biology-minded mini scientist!
Drop your little jellyfish in a plastic water bottle and squeeze to make him bob and dance.
Your pack includes one coloured plastic jellyfish. Requires a refillable water bottle (not included).
How to squeeze and use:
- Squeeze the bottle hard and your jellyfish will sink quickly. Similarly, your jellyfish will float up when you let go.
- When your jellyfish is moving up, try squeezing and releasing the bottle over and over again. Your jellyfish will rotate and dance as it moves back up the bottle!
- Adjust your holding pressure to keep your jellyfish still in the water.
- Colours chosen at random.
Please read the package instructions prior to use.
