Make science cool by these 10 cool chemistry experiments at home

Chemistry is king when it comes to making science cool! Here are 10 completely awesome chemistry experiments you can try.

01 of 10

Experiment #1:

Piece of Copper in nitric acid

Copper reaction Cool chemistry experiments

When you place a piece of copper in the nitric acid, the Cu 2+ ions and the nitrate ions coordinate to color the solution green and then brown-green. If you dilute the solution, the water moves the nitrate ions around the copper and the solution turns blue.

Experiment #2:

Hydrogen peroxide with potassium iodide(Elephant toothpaste reaction)

Elephant toothpaste reaction. 

Lovingly known as elephant toothpaste, the chemical reaction between peroxide and potassium iodide spurts out from a column of foam. If you add food coloring, you can customize the “toothpaste” for the colorful holiday themes. More ”

Sodium metal in a glass bowl of red sunflower water producing sodium hydroxide and hydrogen. 

Any of the alkali metals will react vigorously in water. With what vigor? The sodium burns bright yellow. Potassium burns purple. Lithium burns red. Cesium basically explodes. Experimentation by descending the group of alkali metals from the periodic table. More ”

Experiment #4

Thermite reaction

The thermite reaction basically shows what would happen if the iron rusted instantly rather than over time. In other words, it burns metal. If the conditions are right, just about any metal will burn. However, the reaction is usually carried out by reacting iron oxide with aluminum:

Fe 2 O 3 + 2Al → 2Fe + Al 2 O 3 + heat and light

If you want a truly amazing display, try placing the mixture inside a block of dry ice and then turning on the mixture.

Experiment #5

colorful fire

Cool chemistry experiments .
The colorful fire rainbow was made using common household chemicals to color the flames.

When the ions are heated in a flame, the electrons become excited, then fall into a lower energy state, emitting photons. Photon energy is characteristic of the chemical and corresponds to specific flame colors. This is the basis of the flame test in analytical chemistry, and it’s fun to experiment with different chemicals to see what colors they produce in a fire. More ”

Experiment #6:

Inflatable polymer balls

Who doesn’t like playing with bouncing balls? The chemical reaction used to make the balls makes a great experience, because you can change the properties of the balls by changing the ratio of the ingredients. More ”

Experiment #7:

Make a Electric tree

Cool chemistry experiments .
This Lichtenberg figure or “electric tree” was formed inside a cube of polymethyl methacrylate.

A Lichtenberg figure or “electric tree” is a recording of the trajectory taken by the electrons during an electrostatic discharge. It is essentially frozen lightning. There are several ways to make an electric tree. All are cool!

  • Make a Fulgurite (Electric tree in the sand)

Experiment #8

A crystal of “Hot Ice”

It is a crystal of sodium acetate trihydrate or hot ice.
A crystal of hot ice.

Hot Ice is a name given to sodium acetate, a chemical that can be made by reacting vinegar and baking soda. A sodium acetate solution can be over-cooled to crystallize on order. Heat is released when the crystals form, so even if it looks like water ice, it is hot. Cool, isn’t it? More ”

Experiment #9

Chemical demonstration of Dog barking

Chemical demonstration of barking dog.

The barking dog is the name given to a chemiluminescent reaction between an exothermic reaction between nitrous oxide or nitrogen monoxide and carbon disulfide. The reaction goes down a tube, emitting blue light and a characteristic “woof” sound.

Another version of the demonstration involves coating the inside of a clear pitcher with alcohol and turning on the steam. The flame front descends into the bottle, which also barks.

  • Make the alcohol bottle

Sulfuric acid and sugar.

When you react sugar with sulfuric acid, the sugar is violently dehydrated. The result is a growing column of carbon black, the warmth and overwhelming smell of burnt caramel. It is a memorable experience!
