You will spend eternity here...

The devil meets him at the gate and says, "Alright, you have died and come to hell. You will spend eternity here, but you get to choose how to spend it. You may choose one of these three doorways. Once you choose a door, you may not change it. So let's get started."

The devil opens Door One. The guy looks in and sees a couple of people standing on their heads on a Concrete floor. The guy says, "No way, let's move on."

The devil opens Door Two. The guy sees a few more people standing on their heads on a Wood floor. The guy says, "No way, let's move on."

The devil opens Door Three. The guy sees a bunch of people standing knee-deep in cow manure drinking coffee. The guy says, "Great, this is the one I will chose." The devil says, "OK, wait right here, I will get you some coffee."

The guy settles in with his coffee thinking that this isn't so bad. What's the big deal?

After about 10 minutes a voice comes over the loud speaker saying, "Coffee break's over. Back on your heads!"

Glass wool

In 1938, R. Games Slayter (died 15 Oct 1964) and John H. Thomas patent glass wool and the machinery to make it. Games Slayter, the driving force behind Owens Corning technology and innovation, sought to make a finer glass fiber material. In 1932, Dale Kleist, a young researcher under Jack Thomas (Slayter's research assistant), working on an unrelated experiment accidentally caused a jet of compressed air to strike a stream of molten glass, resulting in fine glass fibers. By Fall 1932, Kleist refined the process by using steam, to make glass fiber material thin enough for commercial fiber glass insulation. From March 1933, Games Slayter directed Jack Thomas in experiments using glass wool, instead of natural or other synthetic fibers, on textile machinery.
