And what did you do after that?
So then I took your barrel and built a long tube above it. Luckily there was already a hole in your barrel lid, so I fixed the long tube there.
With this long tube, which reached the second floor, I filled the barrel with water.
And then it just happened!
Because of the enormous water pressure, the barrel went to pieces, unfortunately.
