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?
