Making a Jellyfish in a bottle is so simple and the girls have been loving their new "pet".
To make a jellyfish in a bottle you will need:
- A clear empty bottle (we used a water bottle)
- A clear plastic bag (similar to the ones used for produce at the grocery store- that's what we used)
- Blue food coloring
Add a small amount of water to the plastic bag and tie it off to create the head of the jellyfish
Trim the tail down a bit so that the bag will flow nicely through the water in the bottle
Then cut the tail into lots of tiny strands to create tentacles
Once cut carefully squeeze the jellyfish into the plastic bottle. Add water and a few drops of blue food coloring if you prefer. Then watch as your kids marvel at their new, life-like pet!
As the bottle is flipped upside down and right side up, the jellyfish swims. It looks so real too!
The Science Behind the Fun- Questions to Ask:
Given the age of Rosie and Jewel, we did this activity for fun and amusement but for older children there is plenty of science to explore!
- Why does the jellyfish always float to the top?
- Can you confuse the jellyfish or trick him in his direction?
- What causes the jellyfish to float in the water?
- How is this jellyfish different than a real jellyfish
This Jellyfish in a bottle makes a fantastic discovery bottle. We added it to our collection and it is already a favorite!
