Then we are forced to improvise. Usefulness of applying physical and chemical principles is demonstrated on flame-resistant fiberglass wick, simple lighters, thermos used for cooking and sperilizing water, utilization electrolysis of brine for generating chlorine for water disinfection, use of PET bottles as simple pressurized filtration device for water purification, and so on., Ladislav Sieger., and Obsahuje bibliografii
