I would like to ask the class with a show of hands, who has never blew a bubble or played with bubbles? I have never met a kid or an adult who could resist bubbles. I believe that there is something unique about a bubble from its fragility, to its rainbow of colors, and to the perfect circle shape. A bubble's life expectancy is usually measured in seconds unless you know how to make a SUPER BUBBLE! So today, I am going to demonstrate how to make a bouncing bubble. MATERIALS:

* 1 cup of distilled water
* 2 tablespoons of dish soap
* 1 tablespoon of glycerin
* Pair of gloves
* Small bubble wand, straw, or pipette


1. Start with 1 cup of distilled water
2. Add 2 tablespoons of dish soap
3. Then, add 1 tablespoon of glycerin
4. Last, mix together all the ingredients
* Allowing your bubble solution to sit undisturbed for at least 24 hours in advance, will allow the bongs in the bubble solution strengthen, which means stronger bubbles. After making up a batch of Bubble Solution with the ingredients listed above.  * Using a small bubble wand start by blowing a bubble. If you are using the pipette instead of the bubble wand, cut the bulb off the top of the pipette, dip it into the bubble solution, and blow into the other end of the pipette. If using a straw just dip and blow out the other end. * Bounce the bubble off of your gloves. It can also be bounced off other fabrics. As you'll soon see, some fabrics work better than others.


Most people don’t know that the bursting of a bubble is caused by contaminates that instantly breaks down the bubble’s mixture and destroys its surface tension. That is why even lightly touching a bubble causes it to burst. So, even though it is just a puff of air trapped in a thin film of soap and water we just need to enjoy the little things in life.
