The amazing pretzel DVD

I was visiting a friend and I remembered that I had a DVD in the car, and offered it to him to check out. It's been in the car for a couple days. I fetch it for him. I'm about to hand it over when I notice it has an odd feel to it. I remove it from the sleeve and the thing is all bent up and curled. The heat of the last couple days softened it and distorted the disk. He said he was going to try to straighten it out. I forgot to find out if it worked. I didn't know it was possible.

Now you know cheap DVDs are in peril of warpage under intense heat conditions!
