Explosion!!!

In the original recipe I read for my Kimchi it stated that you needed to unscrew the lid and let the CO2 out. Otherwise, the pressure would build up. Well I forgot to do this on my first batch of Kimchi. One day I came home and I noticed my kimchi was leaking. Not just a small amount. It was leaking all over my countertop and on to the floor. I instantly remembered that I hadn't opened the container to let the pressure out. So I immediately untwisted the lid. As soon as I did this it exploded everywhere! As if you shook a bottle of soda and opened it. What a mess! So now I have been sure to open my Kimchi in sink daily. Lesson learned!
