No, I cannot understand what’s being said here. But I can understand the gist of what’s happening. These two Norwegian guys have decided to pour dozens of bags of instant coffee into a hot water heater in a house. (I really, really hope it’s not their hot water heater, in their house). The idea being that they want truly instant coffee. This is impressive on their part. Mostly because of how ingenious it is. It’s pretty stupid though. The grounds will clog up pipes, and the acidity of the coffee will not do good things to the plumbing. But that’s why I said I hope it’s not their own equipment they’re messing with.
