What is difference between the two. I am trying to compare the two in pipe form. Which one is stronger, what about prices?
I think the fire department would be your best bet. I'm sure they have a website. If not drop by your local fire department. They would be very glad to help you out. They would like to see someone taking an interest in things like that.
Water does not always put out fires Some fires can burn under water. There is a special type of blowtorch that can produce flames under water And if you add water to a grease fire, the flames will get bigger
