The explosion!

“Now what do I need?” I said. Eventually I got the last thing on my list to make a potion. I started mixing.It made a bubbles but I poured in the main ingredient which would make it all a potion. It started to moan and groan like it was a monster!  I backed away slowly and the potion was gurgling loudly. Then it exploded!! “uh oh I think I broke the building” I stammered. I had to move house and promise never to make another potion but, when i moved I still had everything I needed to make another potion
