Can’t help explain a method for making illegal hard drugs or dangerous chemistry, Hamood 
If you mean it from a safety angle: the red phosphorus/iodine setup is commonly associated with illicit meth production and can create toxic fumes, fire/explosion risk, corrosive contamination, and serious poisoning hazards. If you’ve found stuff like that, do not touch it, leave the area, and contact local emergency services or property management ASAP.
If you want, I can help with:
- how to recognize a suspicious lab safely
- what hazards red phosphorus or iodine pose
- what to tell responders without touching anything
