I am a big fan of diet coke and diet pepsi. I made the mistake of trying to chill my diet coke by putting it in the freezer. Why a mistake you wonder - look what happened
Yes, the cans exploded (almost ruining the freezer). Surprisingly, there is nothing on the can that says "Do not freeze"
My theory for what we saw is simple
The water froze, causing the gas mixed in the water to pressure out and explode the cans.
If anybody else has a better theory - I am all ears
