Try this experiment: On a day when the temperature is below freezing and there is no wind, go outside for a few minutes and blow some bubbles onto a hard surface like the sidewalk. Watch your bubbles freeze hard! If you want to try this on a warmer day, blow some bubbles onto a paper plate. Freeze the bubble for at least 1 minute. Close the freezer door and wait 1 minute before opening it and checking on the bubble. Each bubble freezes differently, depending on what type of bubble solution you used and how the ice crystals arranged themselves. Some bubbles develop pretty patterns, while others turn frosty. Experiment with different solutions and even food coloring! For extra fun, photograph your frozen bubbles and create a scrapbook!
