If you want a truly stunning display, try placing the mixture inside a block of dry ice and then lighting the mixture. Bubbles It happens so quickly that you can form crystal towers as you pour the liquid into a dish. If they develop a white precipitant, lightly rinse them but don't dissolve too much crystal. The snowflakes sparkle really nicely. The demonstrations in this chapter present special hazards, since most involve very hot or extremely cold substances, volatile chemicals, fragile glassware, high-pressure gases or evacuated containers. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! She has taught science courses at the high school, college, and graduate levels. To understand what is needed to achieve effective cleaning, it is helpful to have a basic knowledge of soap and detergent chemistry.

It's basically frozen lightning. The Briggs-Rauscher oscillating clock (clear-amber-blue) may be the best-known color change demo, but there are several colors of clock reactions, mostly involving acid-base reactions to produce the colors. Potassium burns violet. How to make fun glycerin soap Although students know fluorine is extremely reactive and usually quite toxic, the fluorine is safely bound to sulfur in this compound, making it safe enough to handle and even to inhale. Most high school chemistry demonstrations are hands-off for students, but this is one they can try at home.
