Demonstration Speech

Duyen Pham INTRODUCTION I would uniform to ask the class with a show of hands, who has never blew a blather or played with bubbles? I have never met a kid or an adult who could resist bubbles. I believe that in that respect is something unique about a bubble from its fragility, to its rainbow of colors, and to the perfect circle shape. A bubbles life expectancy is commonly 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 travelling bag soap * 1 tablespoon of glycerin * Pair of gloves * Small bubble wand, straw, or pipette step . 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 still for at least 24 hours in advance, will allow the bongs in the bubble solution strengthen, which gist stronger bu bbles. After making up a batch of Bubble Solution with the ingredients listed above. * Using a pocket-sized bubble wand start by blowing a bubble. If you are utilize the pipette instead of the bubble wand, cut the bulb dispatch 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 youll soon see, some fabrics work go than others. CONCLUSION Most people dont know that the bursting of a bubble is caused by contaminates that right away breaks down the bubbles 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.
