In school one day, the teacher decided that for science class she would teach her young pupils about raw materials.
She stood in the front of the class and said, “Children, if you could have one raw material in the world, what would it be?”
Little Stevie raised his hand and said “I would want gold Miss, because gold is worth a lot of money and I could buy a Corvette.”
The teacher nodded and called on little Susie.
Little Susie said, “I would want platinum because platinum is worth more than gold and I could buy a Porsche”
The teacher smiled and then called on Little Johnny.
Little Johnny stood up and said, “I would want silicon.”
The teacher said, “Johnny, why silicon?”
“Because my mom has two bags of it and you should see all the sports cars parked outside of our house!!”
