A mysterious building had been erected on the outskirts of a small town. It was shrouded in mystery. All that was known about it was that it was a chemical laboratory. An old farmer, driving past the place after work had been started, and seeing a man in the doorway, called to him:
"What be ye doin' in this place?"
"We are searching for a universal solvent - something that will dissolve all things," said the chemist.
"What good will thet be?"
"Imagine, sir! It will dissolve all things. If we want a solution of iron, glass, gold - anything, all that we have to do is to drop it in this solution."
"Fine," said the farmer, "fine! What be ye goin' to keep it in?"
