Were you afraid of performing experiments at your school? were you scared of knowing what will happen when you'll combine those acids? Never fear. Your love of science will soon be restored with the incredible chemical reactions featured below. They're all real, and they've been entertaining people for years. Check them out...and probably don't try them at home.

Gallium Melts At Room Temperature.

Gallium melts at room temperature.
This silvery metal has a melting point of around 85 degrees Fahrenheit. It is used to make alloys with low melting points, as well as in electronics.

If you inhaled it, it would make your vocal cords vibrate much more slowly and make your voice sound lower. This is the opposite reaction to inhaling helium.

Dry Ice And Water Make A Giant Bubble.

Dry ice sublimes, meaning it goes directly from a solid to gas. This results in the vapor you see here. It also creates a ton of cold, cloudy fog, and is used in special effects.

Water Forms A Bridge.

By introducing a current, water molecules become more strongly bonded, forming this "bridge" between two containers.

White Tin Turns To Gray Tin.

When the temperature drops below 13 Celsius, white tin (known as beta tin) becomes a more brittle gray version of itself (called gray or alpha tin). Tin decomposes at cool temperatures in a reaction known as "tin pest."

Electrical Treeing.

This happens when a surge of electricity goes through a solid insulation material. The electricity fans out like lightning, creating these tree-like patterns throughout the material.

The Belousov-Zhabotinsky Reaction.

This reaction usually manifests as a solution changing back and forth from one color to another, while never reaching equilibrium. It's so weird that the chemist who discovered it had his work rejected because he couldn't explain what was happening.

Sodium Acetate Solidifies At The Drop Of A Hat (sometimes Literally).

This liquid forms "hot ice," or salt crystals in reaction to almost anything. This gives it the appearance of rapidly freezing water. The crystallization produces heat, which makes this the active ingredient in heating pads. It's also edible, and is mostly known for its part in "salt and vinegar" chip flavoring. Yum.

Nitinol Remembers.

Nitinol is a titanium and nickel alloy, and is 30 times more elastic than other metals. It is also able to snap back to its original shape with a minor change in temperature.

This is hydrophobic sand, which reverts to its dry form when taken out of the water.

Wake Up Your Food.

Sodium chloride in soy sauce triggers muscular spasms in cuttlefish. Though it's already dead, its tissue can still react to stimuli, hence the dance you see here.
