Leave it to a teacher in Minnesota to come up with such a wacky idea as to freezing a towel into the shape of a sled, Of course you could only use it on days when it is super cold.

I remember as a kid my friends and I all had the red 2-3 person plastic sleds with the yellow handles. They were cheap and super fast, but we were lucky if they would last the whole day without getting a hole in them. I am sure my mom would have been thrilled If I would have grabbed a beach towel to go sledding, this is awesome though!
