In this month's edition of "DIY Chemistry," we delve into the world of intriguing experiments you can conduct in the comfort of your own home. For this issue, we have a fascinating contribution from an anonymous author who shares a unique one-pot method for creating a crystalline substance. The instructions are as follows:

1. Gather the necessary materials: a 2-liter plastic soda bottle, camping stove, and basic camping fuel, a digital scale, a long-handled spoon, a large rubber band, a pair of safety goggles, and several other easily obtainable items (which we will not detail here).

2. Put on your safety goggles. Find a well-ventilated area, preferably outdoors, and set up your camping stove.

3. Using your digital scale, weigh the pseudoephedrine (available at most pharmacies) and anhydrous ammonia (available at farming supply stores) according to the anonymous author's specified ratio.

4. Carefully combine the ingredients in the 2-liter plastic soda bottle, following the author's specific mixing instructions.

5. Secure the lid on the bottle using the large rubber band, ensuring it is tight and leak-free.

6. Place the bottle on the camping stove and carefully heat it, following the author's specified heating instructions.

7. Observe the formation of a crystalline substance in the bottle, which should occur within a certain time frame.

8. Once the process is complete, carefully dispose of the waste materials according to local regulations, and keep the crystalline substance for further experimentation or recreational purposes.
