When checking tyre pressures at a service station: remove all caps first

For someone like me, that'd be a sure-fire way to lose tyre caps.

you only do it once! I put them in the dip near the speedo. Soon as I look at my speed I see the problem. I once put them on the flute near the windscreen wipers. When I finally realised - they had blown away.

Then it's the 'punty end'?

So right you don't even know! The rod that glass blowers use to hold a glass object, while making, is called a punty rod because it is pointed. This is not the hollow one that they use to form the bubble. When finishing the open end of (say) a goblet, they attach it to the punty rod then cut and smooth the open end. In fact really old goblets and wine glasses have a rough bottom where they severed the punty rod. These days a blow torch is used to smooth that off. There was a TV wordless documentary recently showing this (BBC4 not currently available, I'm afraid).
