Have you ever watched a bubble freeze? Let's bundle up, grab a few household materials, and go outside to watch what happens when you blow bubbles outside on a cold snowy day.

There's some science behind this fun snow day activity. Check it out:

• Bubble solution—commercial or homemade (recipe provided below)
• Bubble wand
• A pile of snow

1. Make sure you have bundled up! It's cold outside!
2. Blow bubbles using a bubble wand like you would in the summer. Aim the bubble wand toward the ground.  
3. The goal is to have the bubbles land on the snow. You might need to kneel in the snow, or use a pile of snow on outdoor furniture, planter or a bush. 
4. Once a bubble lands on the snow, observe the bubble for a few minutes. Watch for the bubble to turn cloudy. 
5. Gently touch the bubble, and observe what happens!

Helpful hints

• Don’t have any bubble solution? Make your own! 
  • Mix 1 cup warm water, 3 tbsp dish soap and 1 tbsp corn syrup in a small bowl.
  • A pipe cleaner can be twisted into a bubble wand.
• If your bubbles don’t want to land on the snow, try catching them on a bubble wand. 
• Blowing bubbles in a protected area of your yard will help the bubbles keep their shape a bit longer.

Bubble solution is made of liquid soap and water. When you blow a bubble, a small amount of water is trapped between layers of soap, creating a film. The soap film traps air to form a bubble. In really cold temperatures, the water freezes in between the layers of soap. The result is a frozen layer that acts like cellophane when it pops!
