To make the solution, dissolve a small amount of table salt in water. The concentration of the solution does not have to be precise, but it should not be too dilute.

5. Soak the Fuel
The next step is to soak the fuel in the sodium chloride solution. The fuel can be any flammable material, such as wood shavings or cotton balls. Soak the material in the solution until it’s completely saturated.

6. Dry the Fuel
After saturating the fuel, it is time to dry it. Spread the fuel out on a flat surface, ensuring that there is no moisture present. Use paper towels or a cloth to blot out any excess solution.

7. Ignite the Fuel
The final step is to ignite the fuel. Set the fuel alight using a match or lighter, and observe the color of the flame. If done correctly, the flame should appear blue instead of the usual yellow or orange.

8. Experiment with Different Materials
While sodium chloride is the most common material used to produce blue fire, there are other materials you can experiment with. Some examples include rubbing alcohol, copper chloride, and methanol. Each of these materials produces a different shade of blue, allowing you to create unique effects.

9. Make a Colored Flame Torch
Another fun experiment is to create a colored flame torch. To make the torch, saturate a piece of cotton string with the desired chemical, such as copper sulfate or boric acid. Tie one end of the string to a stick, then set the other end alight. The flame on the string will produce a colorful flame.

10. Conclusion
In conclusion, making fire blue is a simple yet exciting experiment that can be done by anyone. By following the steps outlined in this article and prioritizing safety, you can create a blue flame that is not only visually appealing but also provides insight into the chemistry of fire.
