Re: Can you freeze soap bubbles? If so, what is the best way to do this?

Dear Tony!

Interesting topic. By what I've heard, it's not too tough. I know two ways to freeze soap bubbles:

1. Go to Antarctica. Look for a place with -40°C or below. Blowing soap bubbles there will be quite tricky, as most of them burst nearly instantly, but some will shrink, get somewhat crippled and fall frozen to the ground.
2. Take an aquarium, or better an insulated styrofoam container of comparable size (some pizza home services use such boxes), and cover its bottom with dry ice. Wait until a CO₂ layer has built up, generate some bubbles and let them sink into the container. You will notice that the bubbles float on the CO₂ layer and eventually freeze. A number of experiments with soap bubbles along with a recipe for long-lasting ones (glycerine is the secret!) can be found here: The Chemistry of Bigger Bubbles
