Could have seriously damaged his hand if he was holding it. I have a permanent scar in my eyebrow from dry ice enclosed in a weak water bottle that exploded a few (4 or so?) feet from my face. There are YouTube videos of people ending up with severe hand damage from 2 liter bottles.

I was cringing reading this article. I would never ever have handled one of these things, based on my experience. I think I would've put it in the fridge, left the house for at least a day, and bought a new fridge based on the damage.
