What do you think would life be if hoses were not invented? Not the pair that women women wear to cover their legs but the snaky tubes that bring liquid or gas from one container to another. How could the firemen fight fires or the gardener water their plants? How can LPG come out of the tank to the stove? How can oxygen be delivered to a patient’s nose? In your life, what products are you using that are dependent on hoses? How will you do if they are gone?
Now, hoses have improved. Have you seen a Delafield teflon hose?
