Make a Rocket

After being cooped up in a classroom for hours, expected to be quiet for a lot of that time, kids need a release. If your child is anything like mine, he will really like things that explode, burn or otherwise self-destruct in some awesome and spectacular way.

A great way to help kids find that release is to provide an outdoor outlet that calls for whoops and hollers – something like making a rocket! Even though kids do some experiments at school, they are usually tame.

Here is one fun, loud rocket experiment most suited to an outside environment that will surely get your kid excited!

Alka Seltzer Rockets

You will need:

-empty film canister

-Alka-Seltzer tablet



1-Place an Alka-Seltzer tablet in the film canister.


2- Add approximately 1cm of water.


3- Fit the lid on the canister, making sure the seal is very tight. This part is critical or the experiment will be a disappointment.


4- Turn the canister upside-down on a flat surface.


5- Stand back!


Bubbles of carbon dioxide gas are given off when the water is added to the Alka-Seltzer tablet. The enclosed space within the canister ensures the gas is contained. Pressure inside the canister rises until there is enough force to bypass the seal of the lid. This pressure exerts enough force to shoot the canister into the air, forming a rocket.
