I watch more movies than TV, but I like the Chiller channel. What I can't stand are the stupid-assed commercials.
There was just one on for a glue. Someone cut a garden hose and glued it back together, turned the water on, and ejaculated, "Look! That's forty pounds of pressure!"
Why does this grate on my nerves? Unless you were picking your nose or wrapping a string around your finger in high school science class, you know that a pound is not a unit of pressure. A pound is a unit of force, or mass. Pounds per area (such as psi) is a unit of pressure, and given a 40 psi source, the hose had considerably less than 40 psi in it, because they were spraying with it. The strength of the glue would have to be measured by the tension on the hose, which depends on many other variables, including the wall thickness, elasticity, and flow.
I don't know why, but that "pounds of pressure" one always raises my blood pressure (not my blood "force").
There's that god damned commercial again. I'm hitting the mute button.
