Here's a new sport that's taking the world by storm: Cheese Racing! The concept is that you throw one of those plastic-wrapped slices of processed cheese onto a hot barbeque. Instead of melting, the plastic puffs up and expands as the cheese inside heats up. If a bunch of people throw their slices onto the grill at the same time, then the winner is the person whose slice fully expands first. I didn't dare try this on my grill to see if the plastic really would expand instead of melting. But based on the pictures on the cheese racing site, I'm guessing that they're telling the truth. The hoax here may be in referring to the stuff inside the plastic as 'cheese.' I believe that 'processed cheese food' is the proper term. (Thanks to Emily de Saint Jores for the link).
