Don’t forget your shovel…

Man shovelling. Shhh!

Aah… the weekend. Time to relax. Recharge. Rejuvenate.

Re… reach for a shovel. (Wasn’t that an S Club 7 song?)

Lift the sewer access hatch.

And start digging.

Through packed “sludge”.

There’s nothing like blocked drains to remind you of one of the essentials of civilisation – good plumbing

Explaining the Japanese nuclear crisis using poo

Once you get away from the explosions and help! Help! Radiation! Head for the hills… All this nuclear meltdown China Syndrome in Japan business gets a bit complicated. Too many millisieverts, half lives, critical masses and atomic bomb memories. Should we all be panicking? Or not?

Without wanting to be too complacent – and sitting far from Japan – I think, on balance, not.

Here are two options for you to make sense of it all.

1. Read this book. Physics for Future Presidents by Richard Muller. (Or he’s here on wikipedia.)

Or check out his University of California at Berkeley lectures on YouTube.

2. Or – watch the children’s version of events, using farting and poo.
