Freeze a Bubble

It's likely that your kids enjoy playing with bubbles.  This is usually a summer activity and if your kids are like mine, they'll spend a good hour blowing bubbles and chasing them around.  However, this isn't just a summer activity.  There's a cool science experiment you can do with bubbles in the winter.  If it's particularly cold outside, the bubble mixture will freeze before the bubble pops.  We had some below zero weather a couple of weeks back, so one day we took the bubble mixture outside and tried to freeze a bubble.  To do so, first blow a bubble like normal and then catch the bubble on the bubble wand.  This may be difficult depending on the bubble mixture.  It was a bit windy out and the bubbles kept popping once they hit the wand.  For us, doing this outside was a failure, but we weren't defeated yet.  We came back in and caught the bubble on the wand inside where it was less windy.  We held the wand inside the freezer for a few moments to get our frozen bubble.  

The only problem with doing it inside is that the bubble mixture will quickly unfreeze once you pull it out of the freezer.  See our bubble less picture below.

There was a nice frozen bubble on the wand, but once we removed it from the freezer, it quickly unfroze and turned back into a liquid.  There's still a bit of frozen bubble mixture stuck to the sides of the wand.  

Give this a shot and hopefully you'll have better luck outside than we did.
