The latest in our irregular series of links to items you may have missed and which interested or amused me. In no special order …

I know about Tibetan singing bowls (I even have a couple) but I had no idea about the existence of the Chinese Singing Fountain Bowl.

Topology is interesting, but also mind-breaking, stuff and the Klein Bottle is just weird. But three, one inside another?!?!

Excellent spoof article taking the p*** out of “top people’s supermarket” Waitrose. Hold on … I shop there!

Could you pass the 11-plus? I did but anyone under about 55 won’t have been given the opportunity. Try these extracts and find out if you’re up to it now — should be easy for an intelligent bunch like you!

Great hairy faces! Well that’s what was at the British Beard and Moustache Championships earlier this month in Brighton. I was going to say only in this country, but I can think of several places which would sport such championships. Bring back Eurotrash!

Enjoy!
