Bubbles can be fun and instructive any time of year. One safety note, bubble solution on floors can be very slippery. Make sure you carefully clean up any spills right away. It usually works best if you let it sit a day or longer before you use it. Try changing the amounts of the ingredients.
Some people use corn syrup instead of glycerine.
Make a loop of wire or get a bubble wand. Take your bubble solution outdoors and dip the bubble maker in the solution. Stand still and watch the bubble solution freeze on the loop. Shake the bubble free. Dip the bubble maker in the solution again.
