With vacations right around the corner, you should be ready for your kids to complain of boredom.

You cannot let them watch Youtube videos or play games on their laptop all day. What better to keep them busy than science? Because…

Form three layers of liquid

For this, you will need:

  1. Juice
  2. Vegetable Oil
  3. Alcohol (if transparent, add a little food color or paint to it)
  4. Transparent jar

Pour the juice, oil and alcohol alongside the walls of the container one by one. Watch how the three arrange themselves in different layers.

Why does this happen? 

This depends upon densities. Rarer fluids rise up while denser fluids sink down.

Naked eggs

The items you will need are:

  1. Vinegar
  2. Water
  3. 2 glass cups
  4. 2 eggs

Pour vinegar and water in two separate cups. Place one egg in water and the other in vinegar. Check the eggs after 5-7 hours and the one in vinegar would be much softer. After a week or more, the shell of the egg in the vinegar will have completely disappeared.

Why does this happen? 

The egg shell is made of calcium carbonate. Since vinegar is an acid, a reaction takes place. The reaction involves the softening, and then the complete dissolution of the shell.

Balloons that fill up by themselves

Your kids are totally going to love this one.

You need:

  1. Balloons
  2. 2-3 plastic bottles (1L – 1.5 L)
  3. Vinegar
  4. Baking Soda
  5. Funnel
  6. Spoon

Using the funnel, fill the bottle with vinegar to about one-thirds. Now add a few spoons of the baking soda and quickly put a balloon on the mouth of the bottle. Watch it inflate. Rub them with your hair and then leave them near the ceiling.

Why does this happen? 

This happens because the reaction between baking soda and vinegar produces carbon dioxide that gets filled in the balloons and makes them rise. Rubbing them with your hair gives them a static charge so they stick to the ceiling,
