TO INFLATE A BALLOON USING VINEGAR AND BAKING SODA!

Let's use vinegar and baking soda to blow a balloon!!


Materials:


A balloon


Water


Baking soda


Lemon juice or a lemon (vinegar works best)


Drinking straw


Small soda bottle (12 ounce or 20ounce)

Instructions

Take the small balloon in your hands and stretch it out a bit to make it a little easier to inflate.

Pour about 1 ounce of water of into the bottom of a small baking soda

Dissolve 1 teaspoon of baking soda into the water with the help of drinking straw.

Pour 3 tablespoon of lemon juice or the lemon juice found in 1 lemon.


Quickly put the mouth of the stretched balloon over the mouth of the soda bottle.

  What is happening???

The balloon slowly inflates due to the presence of carbon-dioxide formed by the reaction of water, baking soda and lemon juice/vinegar

A LEMONADE-STRAW CAN GO THROUGH A POTATO!!!!

Let's try to make a lemonade-straw go through a potato!


Materials:


A potato (Not boiled)


A lemonade-straw

Instructions

Just try to insert the straw through the potato. Does the straw goes through?? No it does not.

Now cover the top opening of the straw with your finger (as shown in the figure below) and strike the potato quickly with the straw and apply the maximum amount of force you can, but be sure the straw is perpendicular to the potato. Does the straw go through??? Yes it does!! 

The straw goes through!!

What happens???

You are holding the potato in your hand; so it is at rest. It is inert. The straw which strikes the potato has a great impulse of force. The pressure of the compressed air inside the straw (which occurs when your finger is covering the top opening of the straw) will keep it hard. That is why the straw goes through!
