16 Striking GIFs Of Chemical & Physical Reactions

There's a subreddit devoted to GIFs of chemical reactions. They are hypnotizing.

1. Sodium polyacrylate and water

Sodium polyacrylate can absorb over 200 times its mass in water.

2. Fluorine reacting with hydrogen in a balloon

3. A neodymium magnet falling through a copper pipe

Magnetic field equilibrium.

4. A kernel of corn popping

5. Deflecting a stream of water with a charged rod

You can also do this (to a lesser extent) by rubbing a balloon on your hair, then holding it next to your running sink.

6. Mercury(II) thiocyanate decomposition

Heating mercury(II) thiocyanate causes it to release toxic gases and decompose into an insoluble brown mass.

7. Hydrogen peroxide mixed with potassium iodide

The iodide catalyzes the decomposition of the hydrogen peroxide. A small amount of dishwashing soap is usually added so that the resultant oxygen is caught in the bubbles, forming a tower of foam.

8. Copper reacting with nitric acid

Oxidation.

9. Electrical treeing

Electrical discharge.

10. Water crystalizing into snow

11. Firework explosion in slow motion

12. Belousov–Zhabotinsky reaction

A slowly propagating chemical oscillation containing bromine and an acid.

13. Lithium on fire

14. A candle lit by its vapor trail

15. Orange LED light immersed in liquid nitrogen
