Universal Solvents
Have you ever heard of the universal solvent? Well basically it’s a solvent that will eat through anything. Or rather, everything. You pour it on the concrete and it will just fizzle away until it all burns up eating stuff. See that’s the thing, it won’t eat its way all the way through the earth. Think about it. As it eats away at whatever it’s eating away, it uses itself up. So if you pour some on a steel table, it will eat through it, then whatever drips to the floor beneath will be a little less. It then eats through the tile, then the concrete, then some soil, and it’s pretty much down to nothing left at that point. But you do have a nice little hole through your table, foundation and the ground beneath.
So, of course, the question at the end of the riddle is, “What do you put it in?” The old anecdote mentions a guy walking into his boss’s office and saying, “Hey, boss, I finally did it! I finally created the universal solvent!” And his boss looks him up and down and says, “Why isn’t it eating through the beaker?”
