Add this to the list of things I didn't know you could do! Frozen bubbles! If you live in an area that reaches below 32F - blow a bubble and catch it on the wand and just watch while it freezes.
You can also make icy crystals where you don't blow a bubble but just let the solution freeze in the wand itself!
If like me, you live in a place where the coldest it gets is 77F you can also make icy bubbles in your freezer. See instructions here.
