This isn't so much "expertise" but more of a handy "hack."Morning Court, hope everyone is well
Today/ this week, I ask you eloquent courtiers to provide some advice in something you’re expert in for us all
Don’t underestimate yourself, you’re probably expert in tens of areas
And feel free to share advice even if it’s of tangential relevance, sometimes it can be satisfying to learn about something very random
Have you ever had to repair PVC piping (such as changing a supply valve to your sink etc) and couldn't get the water to stop dripping, to make a good glue joint?
If so, pull a chunk of cheap, store bought white bread from the center of the slice, roll it tightly into a ball, shove it into the end of the piping, quickly dry it, glue it, and make your repair.
When the water pressure is restored, it'll soften the bread and push it through with no problem....
I was 50 before I was shown this trick and wish I'd learned it while in my teens.
