Diet Coke Explosion

I guess the top shelf of our refrigerator gets a little chilly cause we heard a huge "POP" one day and I was like "Noah, did something in our refrigerator fall?". So he opened it to check and this is what we saw...

...trust me it was ALL over our fridge...
...and this is what noah looked like...
....and this is just part of the fridge taken out...
