Inspecting gadgets
This is an interesting article on money-saving, environmentally friendly gadgets I read on Yahoo! recently.
One of said gadgets is a staple-free stapler that works by cutting and folding the sheets as you press down. The description of this item includes the fact that if every office worker in Britain saved one staple per day, in one year, 72 tonnes of metal would be saved. This sounds incredible (in the literal sense), but if you ‘do the math’, it’s actually true.
If a staple weighs about 32 milligrams, and there are 10 million UK office workers, each working 225 days a year, then 32 x 10,000,000 x 225 = 72,000,000,000 mg. Knock off three zeroes to turn it into grammes, then three more to make kilograms, and three more to make tonnes.
