How do you make a potassium nitrate rocket?

How do you make a potassium nitrate rocket?

This method involves melting a mixture of sugary fuel and chemical oxidizer (the potassium nitrate) over an electric hot plate and then pouring it into a paper rocket body where it solidifies into a rock-hard casting containing an incredible amount of chemical energy.

How do you make homemade rocket fuel?


  1. 58 grams (2.0 oz) potassium nitrate (aka KNO3/saltpeter)
  2. 29 grams (1.0 oz) granulated white sugar.
  3. 13 millilitres (0.055 c) Karo syrup.
  4. 30 millilitres (0.13 c) distilled water.

Is making rocket fuel illegal?

A traditional sugar propellant formulation is typically prepared in a 65:35 (13:7) oxidizer to fuel ratio. There are many different methods for preparation of a sugar-based rocket propellant. In the United States, rocket candy motors are legal to make, but illegal to transport without a low explosives users permit.

How do you make the best sugar rocket?

Mix your propellant in a rock tumbler for 6-10 hours for best results. A rock tumbler will mix your ingredients more thoroughly so your rocket has better thrust. Put the potassium nitrate and powdered sugar into a rock tumbler. Then, bring your rock tumbler outside while you mix the propellant.

What happens if you mix potassium nitrate and sugar?

That is the reaction that is commonly found in sparklers, a combination of potassium nitrate, sugar, and metal filings. The reaction of sugar and nitrate makes heat, and the heat excites the metal filings, causing them to be oxidized and emit light. It is also the principal reaction in sugar rocket fuel.

How high can a homemade rocket go?

Estes model rockets fly from 100 feet to 2,500 feet high! It all depends on the size and design of the model rocket and the Estes engine(s) used to launch it. Each Estes model rocket is tested numerous times, before it goes to market, to determine which engines are best for flight and the altitudes that can be reached.

What are three types of rocket fuels?

Most liquid chemical rockets use two separate propellants: a fuel and an oxidizer. Typical fuels include kerosene, alcohol, hydrazine and its derivatives, and liquid hydrogen. Many others have been tested and used. Oxidizers include nitric acid, nitrogen tetroxide, liquid oxygen, and liquid fluorine.

What are the dangers of potassium nitrate?

* Breathing Potassium Nitrate can irritate the nose and throat causing sneezing and coughing. * High levels can interfere with the ability of the blood to carry Oxygen causing headache, fatigue, dizziness, and a blue color to the skin and lips (methemoglobinemia).

What is the common name of potassium nitrate?

The chemical compound potassium nitrate is a naturally occurring mineral source of nitrogen. It is a nitrate with chemical formula KNO3. Its common names include saltpetre (from Medieval Latin sal petrae: “stone salt” or possibly “Salt of Petra”), American English salt peter, Nitrate of potash and nitre.

Whats the highest a homemade rocket has gone?

On May 17, 2004, Civilian Space eXploration Team (CSXT) successfully achieved the first officially verified flight of an amateur high-power rocket into space, achieving an altitude of 116 km (72 mi).

How to make sugar rockets with potassium nitrate?

Open the tub and dump the mixture onto the 40-mesh screen. Gently rub the fuel through the screen with a gloved hand. Put the fuel back into the tub again, close it, and repeat the shaking. Repeat the screening one more time. Intimate mixing of the chemicals is important for the fuel to work well in rocket motors.

How to make potassium nitrate at home by WonderHowTo?

How To Make potassium nitrate at home. To test it, mix two parts potassium nitrate with one part sugar and light it up. It should burn with a purple/pinkish flame. Brought to you by one of WonderHowTo’s favorite scientists, NurdRage.

What kind of salt do you use to make 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 are the ingredients for a rocket motor?

[KoD] and [Navic] are building solid propellant motors using sugar and potassium nitrate. They cook up the two ingredients along with water and a bonding agent.
