In school one day the teacher decided that in science class
she would teach about materials.

So 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,
because gold is worth a lot of money and I could buy a
Porsche."

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 Corvette"

The teacher smiled and then called on Little Johnny. Little
Johnny stood up and said, "I would want silicon."

The teacher said, "Why Johnny?"

He responded by saying, "Because my mom has two bags of
it and you should see all the sports cars outside our house!!"
