Cool chemistry in action.Here are ten amazing and cool chemical reactions . If you are lucky, you can try these chemical reactions in a laboratory or have them demonstrated.

Thermite and ice
The thermite reaction is essentially an example of what happens when the metal burns. What happens if you perform the thermite reaction on a block of ice? You get a spectacular explosion! The reaction is so amazing that the Mythbusters team tested it and verified that it was real.

Briggs-Rauscher Horloge Oscillante
This chemical reaction is amazing because it involves a cyclic color change . A colorless solution runs through light blue, amber yellow and dark blue for several minutes. Like most color change reactions, this demonstration is a good example of a redox or redox reaction.

Hot ice cream or sodium acetate
Sodium acetate is a chemical that can be over-cooled. This means that it can remain liquid below its normal freezing point. The incredible part of this reaction is the initiation of crystallization. Pour the supercooled sodium acetate onto a surface and it will solidify as you look, forming towers and other interesting shapes. The chemical is also known as ” hot ice ” because crystallization occurs at room temperature , producing crystals that look like ice cubes .

Reaction to magnesium and dry ice
When lit, magnesium produces a very bright white light. This is why hand fireworks are so bright. While you may think that fire needs oxygen, this reaction demonstrates that carbon dioxide and magnesium are involved in a displacement reaction that produces fire without oxygen gas. When you light magnesium inside a block of dry ice, you get a bright light.

Dance Gummi Bear Reaction
Dancing Gummi Bear is a reaction between sugar and potassium chlorate , producing a purple fire and lots of heat. This is a great introduction to the art of pyrotechnics, as sugar and potassium chlorate are representative of a fuel and an oxidant, like those found in fireworks. There is nothing magical about the Gummi bear. You can use any candy to provide sugar. Depending on how you perform the reaction, you may get more than one immolation than a bear tango. It’s perfect.

When the metal salts are heated, the ions emit various colors of light. If you heat the metals in a flame, you get a color fire. Although you can not mix different metals together to get a fire rainbow effect -en- sky , if you line up in a row, you can get all the colored flames.
07 of 10
Sodium and chlorine reaction
Sodium and chlorine react to form sodium chloride or table salt . Sodium and chlorine gas don’t do much until a drop of water is added to get things done. It is a reaction very exothermic which generates a lot of heat and light.
08 of 10
Elephant toothpaste reaction
The elephant’s toothpaste reaction is the decomposition of hydrogen peroxide, catalyzed by the iodide ion. The reaction produces a ton of hot, steamy foam, and can be colored or even striped to look like some toothpaste. Why is it called the “elephant toothpaste reaction”? Only an elephant tusk needs a toothpaste strip as wide as that produced by this amazing reaction!

If you cool the water below freezing , it doesn’t always freeze. Sometimes it supercools , which allows you to freeze it to order. In addition to looking very cool, the crystallization of supercooled water in the ice is a good reaction, because just about anyone can get a bottle of water to try it out for themselves.

Mixing sugar (sucrose) with sulfuric acid produces carbon and steam. However, sugar does not just darken! The carbon forms a smoking tower that comes out of a beaker or a glass, resembling a black snake . The reaction also smells like burnt sugar. Another interesting chemical reaction is to combine sugar with baking soda. Combustion of the mixture produces a safe “black snake ” firework which burns like a coil of black ash, but does not explode.
