Speedy fish experiment
Watch the fish swim crazily across the water as your kids learn about surface tension with this fish-friendly kids’ science experiment. Have fun with your kids as they explore the wonders of science today.
What you need:
- Water
- A bowl
- Liquid soap
- Cardboard
- Scissors
Number of players:
1+
Activity:
Cut out little fish shapes from the cardboard.
Fill the bowl with water.
Carefully float the cardboard fish on the top of the water.
Add a drop of liquid dish soap behind the fish’s tail.
What happens? The fish swims away!
Notes:
- This happens because the dish soap breaks the water’s surface tension, allowing the water to pull the fish away from the soap. How cool is that?
