Grow Bismuth Crystals

Image
Are you looking for a gorgeous crystal to grow? Try bismuth crystals. Bismuth is a metal that forms interesting geometrical 'hopper' crystals that are rainbow-colored from the thin oxide layer that forms on them. You can get bismuth at a sporting goods store or you can order it online. The crystals only take a matter of seconds to grow, so give it a try! Bismuth Crystal Materials bismuth 2 stainless steel measuring cups or aluminum cans that you have cut in half to make shallow bowls a stovetop, hot plate, or propane torch You have a few different options for obtaining bismuth. You can use non-lead fishing sinkers (for example, Eagle Claw makes non-lead sinkers using bismuth), you can use non-lead ammunition (the shot will say it is made from bismuth on the label), or you can buy bismuth metal. The quality of crystals you obtain depends in part on the purity of the metal, so make sure you are using bismuth and not an alloy. Grow Bismuth Crystals Bism...

Colored Flame Spray Bottles

Image
Colored flame spray bottles are one of the easiest and most memorable chemistry demonstrations you can perform! The demo also makes a great chemistry "magic" trick, although of course it is based on the emission spectra seen in flame tests. Chemist Mitch at the Museum of Science and Industry in Chicago shows how to perform this demonstration safely and effectively:. Wear protective clothing. Lab coats look cool, plus they protect your clothes. You can't see this, but Mitch is wearing long pants and shoes that cover his feet. Wear your safety goggles. Modern safety goggles are comfortable, fashionable and safe. Direct the spray away from the audience. When the alcohol hits the flame, it produces a fairly dramatic plume of flame. You don't need to scare anyone or ignite any hair. If you have one, use a clear blast shield. In this demonstration, droplets of liquid can splash harmlessly on the inside of the shield, controlling the flame. Have fun with i...

On This Day in Science History - December 29 - Charles Goodyear

December 29 th is the birthday of the man who discovered the process to vulcanize rubber. Charles Goodyear spent several years trying to find a method to convert rubber into a substance that would not turn brittle in the cold or turn to goo in the heat. His early attempts found rubber that would rot after time or still turn sticky in heat. He ultimately found the answer by accident. He spilled a mixture of rubber mixed with sulfur on a hot stove and cured the rubber into a solid mass. After he patented his process, he started a small company to find uses for his rubber. Unfortunately, he spent most of his efforts on defending his patents and in lawsuits and his business failed. The Goodyear Tire and Rubber Company had nothing to do with Charles Goodyear and was formed 38 years after his death in 1860.
