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.
Due to its density, it's often used in electrical insulation.
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 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.
Okay, not literally, but these freaky tentacles really do form in this heat-triggered reaction.
By introducing a current, water molecules become more strongly bonded, forming this "bridge" between two containers.
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."
This is sped up, but the sulfuric acid dehydrates the sugar, leaving water and carbon behind in this column shape.
When snake venom is mixed with blood, the result is this congealed mass. Gross.
This happens when mercury is able to penetrate aluminum's oxide layer.
This reaction is called the "Pharaoh's serpent," and the resulting snake-like solid was once sold as a toy. Unfortunately, it's incredibly toxic and resulted in the deaths of several children.
It reminds us of a certain science experiment.
You've probably seen this, but it happens really fast. This is what's actually going on in slow-motion.
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.
This produces a beautiful, but irritating, purple plume of iodine vapor, as well as heat and light.
Contact with organic materials causes the formation of gas bubbles and tissue destruction. Contrary to popular belief, it's actually not a good idea to put this on a wound.
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.
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 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.
Water beading on a surface is an example of hydrophobia, but some substances are so hydrophobic that they achieve perfect spheres of water.
This is hydrophobic sand, which reverts to its dry form when taken out of the water.
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.
