What is the cleanest rocket fuel?

Hydrogen
Hydrogen. Many early rocket theorists believed that hydrogen would be a marvelous propellant, since it gives the highest specific impulse. It is also considered the cleanest when oxidized with oxygen because the only by-product is water.

How do you make the best rocket fuel?

Add 58 grams (2.0 oz) of potassium nitrate and 29 grams (1.0 oz) of sugar to the container, then shake it vigorously until they’re evenly distributed. In order for your rocket fuel to burn properly, it’s important that your dry ingredients be well-sifted.

How do you make potassium nitrate at home?

Just mix 40 grams of ammonium nitrate with 100mL of water and stir until dissolved. Filter the mixture directly into 37 grams of potassium chloride. Gently heat until completely dissolved, do not boil. Cool the mixture to 0 Celsius in the freezer or on an ice bath.

What can I use to make rocket fuel?

For this project, I wanted to use some kitchen chemistry and a few common household items to test out a few different methods for making rocket fuel. This type of rocket fuel is commonly referred to as “R-Candy” The main components of this composition are a brand of stump remover, which is 100\% potassium nitrate (KNO3), and plain white table sugar.

Is potassium nitrate a good source of rocket fuel?

Well, the availability of potassium nitrate varies upon location (concerning legal matters), although it isn’t your only option to make cheap, easy homemade rocket fuel. Potassium nitrate is an oxidising salt, a nitrate salt to be more specific. There are other nitrate salts, such as sodium nitrate and ammonium nitrate.

What can I add to a fuel-oxidizer mixture?

You can add stuff to your fuel-oxidizer mixture, like powdered aluminum, iron oxide, and sulfur (in minute amounts, less that 30\%) Try black powder, it does contain potassium nitrate, but it is sold in WalMart, Bi-Mart, and many other places as black powder for reloading black powdered guns. That’s probably your best bet. Remember, fire hurts.

Why don’t you use KNO3?

The reason that I dont want to use KNO3 is that the stores that I know of that supply me with it have all slowly stopped supplying it due to bans and are forced to re-stock.One store does sell a fertilizer with soluble potassium oxide and nitrogen but thats as close as it gets to pottasium nitrate
