HCl (Acid): A strong, sour liquid that eats through metals and reacts "grumpily" with almost everything.

NaOH (Base): A "slippery" chemical (like concentrated soap) that neutralizes acids to make salt water.

H2O (Water): The universal solvent. It’s neutral and used to dilute or trigger reactive metals.

Mineral Oil: A thick liquid that floats on water because it’s lighter (less dense) and doesn't mix.

Potassium (K): An extremely "energetic" metal. It hates being in water so much that it explodes on contact.

Ethanol: Pure alcohol. It’s very flammable and will "pop" if the temperature gets too high.

Indicator: A chemical "spy." It changes color to tell you if a liquid is an Acid (Red) or a Base (Blue).

Magnesium: A lightweight metal that fizzles and releases Hydrogen gas when it touches acid.

Sodium (Na): A reactive metal similar to potassium; it fizzes, spins, and can catch fire on water.

KMnO4: Deep purple crystals (Potassium Permanganate) that act as a very strong oxidizer.

Peroxide (H2O2): A clear liquid packed with extra oxygen that makes other reactions foam up.

Glycerin: A heavy, syrupy liquid that sinks in water; it can catch fire when mixed with KMnO4.

Silver Nitrate: A clear liquid used to grow silver crystals when it reacts with metals like copper.

Copper (Cu): A reddish-brown metal that is a great conductor and reacts to create silver "trees."

REACTION LIST

Violent & Explosive Reactions

Elephant Toothpaste: Mix Peroxide (H2O2) + KMnO4. The purple crystals rapidly break down the peroxide, releasing a massive fountain of oxygen gas and foam.
The Fire Fountain: Mix KMnO4 + Glycerin. After a few seconds of "hissing" and smoke, the mixture will spontaneously burst into bright purple flames.
Potassium Explosion: Drop Potassium (K) into H2O (Water) or (HCI)Acid. It reacts instantly with a lilac-purple flame and a loud bang.
Sodium Fizz: Drop Sodium (Na) into H2O (Water). It melts into a silver ball, zips across the surface, and produces hydrogen gas (and sometimes a small explosion).
The Flash Point: Add Ethanol and heat the beaker above 95°C (by mixing Acid and Base first). Results in EXPLOSION! Alcohol is highly flammable at high heat.

Metal & Acid Reactions

The Silver Tree: Add Copper (Cu) to Silver Nitrate. The copper will slowly dissolve into the liquid, while beautiful, shiny silver crystals grow all over the metal surface.
Hydrogen Fizz: Add Magnesium to HCl (Acid). The metal will dissolve rapidly, releasing a "fizz" of hydrogen gas bubbles.
Copper Oxidation: Mix Copper (Cu) with HCl (Acid) and Peroxide (H2O2). This will slowly dissolve the copper and turn the liquid a bright green or blue color.

Color & pH Reactions

Neutralization: Mix HCl (Acid) and NaOH (Base). If you add Indicator first, you can watch the liquid shift from Red (Acid) to Blue (Base) as you balance the pH to create clear salt water.
The Purple Potion: Add KMnO4 to H2O (Water). Even a tiny crystal will turn the clear water into a deep, vibrant magenta liquid.

Density & Mixing Experiments

The Density Tower: Carefully pour Glycerin, then H2O (Water), then Mineral Oil, then Ethanol. Because they have different weights (densities) and some don't mix, they will stack in colorful layers.
The Oil Slick: Pour Mineral Oil into H2O (Water). The oil will float perfectly on top because it is lighter and "hates" mixing with water.
