1. Jar of gas igniting; 2. Chlorine tablet + rubbing alcohol in closed bottle; 3. Blood in hydrogen peroxide; How it works: An enzyme in blood called catalase turns the hydrogen peroxide into water (H2O) and oxygen gas (O2), creating a foam of oxygen bubbles. 4. Dry ice + dish soap How it works: Instead of the dry ice just bubbling in the water to make a cloud, the soap in the water traps the carbon dioxide and water vapor in the form of a bubble. 5. Gallium in hot water How it works: Gallium, used mostly in electronics has a melting point of 85 degrees Farenheit and will melt if held in your hand. 6. A match lighting How it works: A matchhead contains red phosphorus, sulfur and potassium chlorate The heat generated from the phosphorus breaks down the potassium chlorate, and in the process, it releases oxygen. The oxygen combines with the sulfur, producing a short-lasting flame we use to light a candle or a cigarette. 7. Hydrogel beads + colored water How it works: Diffusion. 8. Snake venom + blood How it works: A single drop of viper venom dripped onto a petri dish of blood makes it clot into a thick chunk of solid matter. This is essentially what happens inside your body if you’re bitten by a poisonous snake, which is terrifying. 9. Burning magnesium + water How it works: Magnesium metals are not affected by water at room temperature; it reacts with water vapor to make magnesium hydroxide and hydrogen gas. Magnesium fires cannot be extinguished by water and must be covered in sand to be put out. 10. Acetone + styrofoam How it works: Styrofoam is made up of polystyrene foam which, when dissolved in acetone, releases the air in the foam, making it to look like you’re dissolving this massive quantity of material into a small volume of liquid. 11. Mercury thiocyanate decomposition How it works: Burning mercury thiocyanate causes it to decompose into three other chemicals. The three other chemicals decompose again into another three chemicals, causing this terrifying creature thing to unfurl from all the expansion. 12. Fire + hydrogen How it works: Hydrogen gas is lighter than air and can be ignited with a flame or spark, resulting in a vivid explosion. This is why we’ve largely switched from hydrogen-powered blimps to helium ones. 13. Mercury + aluminum How it works: Mercury penetrates the protective oxide (rust) layer of the aluminum, allowing it to rust much more rapidly. This is one of many reasons you should never bring mercury on an airplane. 14. Iron + copper sulfate solution How it works: The iron replaces the copper in the solution, turning copper sulfate into iron sulfate (FeSO4). Pure copper collects on the iron. 15. Lithium on fire 16. A candle lit by its vapor trail 17. Orange LED light immersed in liquid nitrogen How it works: The wavelength & frequency of the light changes as it loses thermal energy. 18. Flammable fluid in a glass jug How it works: Isopropyl alcohol, most likely. 19. Sodium polyacrylate and water How it works: So
