INTRODUCTION:
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

STEPS:

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
EXPERIMENT:
* 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.

CONCLUSION:

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

    The secret to a good bubble is something called surface tension, an invisible bond that holds water molecules together. Water is a polar molecule, so it has plus and minus ends just like magnets that attract each other. When the water molecules align with each other they stick together, creating surface tension.…

    The Greeks were chewing a type of gum as early as the year 50 AD. This proves that gum has been existing for a long time but the first bubble gum wasn’t invented until 1906 by a guy name, Frank Fleer. He called his oh so sticky gum blibber-blubber. Surprisingly Frank’s gum wasn’t a hit, he barely sold any due to the fact that every time you blew a bubble, the gum would stick to your skin and you had to scrub it off with turpentine. Ouch, how painful!…

    The bubble may seem close to perfection from your perception however its true quality and feature is one sticky disaster. The bubble has four main elements that mold its physical body as a whole: water, sugar, glycerin, and soap. As the bubble ascended towards the sky, it finally ventured to its demise of breaking apart into minuscule drops of water, soap, sugar, and glycerin. Not to mention, bubbles have naturally acquired a prodigious aroma that enchants a majority of people’s noses.…

    2.1 History: A person called Walter E. Diemer, was an accountant for the Fleer Chewing Gum Company during the year 1928. The company which was located in Philadelphia, was experimenting with new gum recipes.
