Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead(II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain through a window.
The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...
The experiment is practised in schools around the world and is often used at open evenings to show the more engaging and entertaining aspects of science in secondary education settings. [2] [3] The experiment shows the amount of energy there is in a piece of candy. Jelly babies [4] or gummy bears [5] are often used for theatrics.

Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1]
The vanishing valentine experiment is another chemical reaction related to the blue bottle experiment. This reaction occurs when water, glucose, sodium hydroxide, and resazurin is mixed in a flask. When the solution is shaken, it turns from light blue to a reddish color. The solution turns back to a light blue after being left to stand for a while.
