So Ive got 13 extract brews done and on my 10th extract brew I did something stupid and figured I would share my experience to warn off new brewers from doing it. So Ive pretty much been using liquid extract as its whats more available from my supplier. one of the problems with liquid is getting all the extract out of the container, so i soaked it in hot water like always. And I scooped up some of the boiling water in the pot to rinse it out, but this time I thought hey if i get a little water (and very little maybe 1/2" in the container) close the container and shake i can clean all the sides off, well it worked, except the water never made it back to the pot, because by the time I closed the lid and went to shake the steam had built enough pressure to blow the lid off and send boiling water all over my face and arms. Luckily i was wearing a sweatshirt and was able to wipe it off immediately and didnt get any bad burns, still hurt like a bitch but no burns. Looking back obviously steam in a closed container equals bomb, but didnt think that much water would be a problem. Lesson Learned
