Metal salts may be identified by the color of flame they produce when they are heated. Learn how to perform the flame test and what the different colors mean.The thermite reaction basically involves burning metal, much as you would burn wood, except with much more spectacular results.You can grow crystals of pure metals. Silver crystals are easy to grow and may be used for decorations or in jewelry.Pennies ordinarily are copper-colored, but you can use chemistry know-how to turn them silver or even gold! No, you won&#39;t be transmuting the copper into precious metal, but you&#39;ll learn how alloys are made.Perform an oxidation-reduction reaction to mirror the interior of a glass ornament with silver. This is a wonderful project for making holiday decorations.You can grow bismuth crystals yourself. The crystals form rapidly from bismuth that you can melt over ordinary cooking heat.Apply a redox reaction to plate a layer of copper over zinc or a galvanize object to make a pretty copper ornament.Suspend an iron compound to make a fluid magnet. This is a more advanced do-it-yourself project. It&#39;s also possible to collect ferrofluid from certain audio speakers and DVD players.Perform a chemical reaction to remove the zinc from the inside of a penny, leaving the copper exterior intact. The result is a hollow penny.There is enough iron metal in a box of breakfast cereal that you can actually see it if you pull it out with a magnet. Here&#39;s how to do it!
