How To Make Rocket Fuel
Dr. Gareth Francis demonstrates how anyone can fire up a miniature rocket at home with an empty film canister and some simple household staples which, when mixed, create a chemical reaction in the form of carbon dioxide, which is what will be used to power the miniature rocket. Dr. Francis explains how to create the chemical reaction you desire with either vinegar and baking soda, or with fizzy tablets and water.
Today, I'm going to show you how to make rocket fuel, to make your own little rockets at home. So, you can fire them up into the air and this is a very safe process. There's nothing that can fire you up in the air, there's nothing dangerous involved but it does give a good explosive effect so that you can get your rocket to fly up into the air.
I've made a rocket already, quite simply with a film canister, a fifty-five millimeter film canister and I've put just some bits of tape on it. You can put wings on it, you can put a nose cone on it. The important thing to remember is not to put any cello tape or anything inside or around the lip of the rocket so that you can get the lid on quite carefully, quite easily, so you can get the lid off.
So, if you get the cello tape in it, it won't work very well. So, the rocket fuel is going to be made from bicarbonates of soda and vinegar. Now, if you put these two things together, you get a chemical reaction.
It gives off carbon dioxide gas and carbon dioxide gas is the gas that you get in lemonade, that's what I'm thinking about, and stuff that makes things sparkly, but there's a lot of volume in the gas so that it quite quickly fills up a volume like this, so that it explodes. And the more of that gas that builds up, then the higher the pressure inside and then that forces the lid off of the bottom and launches the rocket in the air. Instead of bicarbonate of soda and vinegar, you could use fizzy tablets, it works just as well.
But, you only need about a quarter of a tablet and some water to make that work. So, I've got my rocket. I'm going to first put a fuel in, which is vinegar, it's easier to add the vinegar first, now, bicarbonate of soda. .
