convertion of colors by adding one to another, Changing of smell mind blowing to pungent, Explosion of lights, rain in a testube. Isnt it all a great fun?
Today im gonna talk about 8 most funny but dangerous chemical reactions.
1. Cesium and water reaction.
The reaction of cesium and water is a small view of a large explosion . Cesium is a reactive alkali of group 1 in the perodic table.
The direct contact of cesium and water forms cesium hydroxide and hydrogen gas is a characteristics chemical reaction of elements of group 1.
The reaction occured so fast that bubble of hydrogen gas forms around alkali metal cesium when the alkali metal exposed into water then the exothermic reaction is occured thus ignition of hydrogen gas
Cs + H2O ➡ Cs(OH) + H2
2.Thermite and ice cube .
Did you ever see a boom by mixing fire and ice cube? Obviously not.
This is possible with the help of thermite which is formed by the mixture of aluminum powder and oxide of meltal . An exothermic redox reaction is occured when the mixure is ignite and the main part is when the igniti part of this thermite is placed in a ice cube then the ice immediately sets on fire with lot of energy evolving in the form of large explosion,
booom!
This reaction is occured with the caution of fire do not try this at home.
3.Elephant toothpaste 😆
Its looking like a great fun! Elephant toothpast? Yes.
Thevreaction of hydrogen peroxided and potassium iodide a huge foamy substance is produced its looking like toothpaste. Sometimes soap is added to make foamy bubbles. Reasonably the name is such.
In this reaction Hydrogen peroxided decomposees fast and the soapy water traps a lot of oxygen molecule resulting in a huge bubble.
4. Na-K alloy and water.
Sodium and potassium are the reactive alkali metal they form oxides in exposer to air thats why they cant be bexposed to air in consideration of purity of metal elements.
Generally sodium and potassium are kept under kerossine/ pertrol like inert substances.
For making Na-K alloy total process is occured under petrol/kerosin i.e outside the air.
This is a violent alloy which also can react with air but more violent in water.
5.Belousov-zhabotinsky reaction.
This reaction is a most funny oscillating chemical reaction.
When Br and and an acid combine carefully and touched with a iron pin the oscillation is occured.
This reaction is a great example of non equilibrium thermodynamics that result in the colorful oscillation of chemicals in the reaction place.
6. Nitrogen tri-iodide explosion.
Nitrogen tri iodide is an explosive substance. Can be easily made at home. The carefull reaction of nitrogen and iodin Makes this explosive then drying this product in oven gives NI3
Is a very reactive compound, a simple touch by a feather can set off contact explosion.
7. Calcium gluconate.
Say first, its a calcium tablet! Used fir calcium deficiency.
Cool. Though its has good perpose of use But when it is heated It causes a great expansion in molecular structure.
Which is look like a grey snake like foam structure caused by the evaporation of water and Dehydration caused by OH- ion present in the gluconate structure. 
8. Barking dog
Nitrogen monoxide and carbon di-sulphide ignition gives a flash of blue light and the most funny thing is a woofing sound.
Wofing sound by chemical reaction! Yes. This is caused by the radily decomposition of combustion process.
