Make a Gas Cannon
Make a gas canon is one easy science experiment that you can do at home with your children. For this experiment you will need :
- a small glass bottle with a tightly fitting cork
- baking soda
- vinegar
- a piece of paper
- water
Now this is step by step :
Put some baking soda into bottle
Dip the cork in water to make it very wet.
Pour some vinegar into the bottle and push in the cork as quickly as you can.
And…Stand Back…!!! The cork will Pop Out!!!
So, How it works?
This is a little explanation about why the cork pop out..
Baking soda is a chemical called sodium bicarbonate. When this stuff mixes with vinegar, it makes a gas called CO2 or Carbon Dioxide. This gas pushes the cork out of the bottle. Most explosives work because a special mixture of chemicals makes a huge amount of gas quickly.
And DO YOU KNOW that some rockets work in the same way with this basic experiment? The fuel in the rockets makes a big blast of gas that can pushes out the end of the rocket and sends it up and along into space.
