Valuable Elements

The teacher asked her students, “If you could have an unlimited supply of any element, which one would you want?”

One boy said, “I would choose gold. It’s worth lots of money and I could buy a Corvette.”

Another boy said, “I would want platinum because it’s worth more than gold and I could buy a Porsche.”

Little Johnny said, “I would want silicon.”

“Why would you want that?” Asked the teacher

“Well my mom got some,” he replied, “and now there’s always a Porsche or Corvette sitting in our driveway.”
