Recipe for Disaster

by | Aug 12, 2022 | Physics, Experiments


In this experiment(recipe for disaster), we will be finding the mixture of the black powder that could create the strongest reaction.


To find out the mixture of black powder that could yield the greatest and enormous reaction.


1. Black mixture will be the mixture of chemicals like Sulfur, Charcoal, and Potassium Nitrate.

2. We hypothesised that this black mixture in the ratio of 6:4:1 would yield the strongest reaction.

3. Gunpowder is a mixture of Potassium Nitrate, Charcoal, and Sulfur.


1. Charcoal

2. Potassium Nitrate

3. Sulfur

4. Pestle

5. Mortar

6. Notebook


Step 1: In the first step, we purchased charcoal, sulfur, and potassium Nitrate from a chemist.

Step 2: We bought mortar, pestle, and all the safety equipment from the science lab of our school.

Step 3: We used different ratios of chemicals to create a mixture of the black powder.

Step 4: We forced them to react after creating the black powder mixtures.

Step 5: We measure the yield of the reaction with the help of reaction time, reaction distance, reaction height, and the unreacted pieces.

Step 6: At last, we recorded our observations.

A Mixture of Potassium Nitrate, Sulfur, and Charcoal


1. The greatest reaction yielded by the mixture of potassium nitrate, sulfur, and charcoal in a ratio of 6:4:1.

2. The reaction with a ratio of 6:4:3 was the fastest reaction among all. But covered the less reaction distance.

3. Apart from this, the other two ratios were not stronger than the reaction’s previously mentioned ratios (6:4:3 and 6:4:1).


1. The hypothesis in which we assumed that the black mixture with a ratio of 6:4:1 would yield the strongest reaction was correct.

2. From the experiment, we found that all four experiments reacted with success. But the one that yielded a larger, stronger, and long-lasting reaction was potassium nitrate, sulfur, and charcoal when reacted in the ratio of 6:4:1.

3. Over a larger time, it produced a larger area, indicating the reaction’s strength. And we learned that the 6:4:1 solution is the strongest of all.


1. Handle all the chemicals with care.

2. Wear gloves and safety glasses.


In this experiment, we created a black mixture and found out which mixture will yield the strongest reaction.
