Light-bulb moments can strike in the most unlikely situations. Legend has it that Sir Isaac Newton came up with his theory of gravity when he observed an apple fall from a tree. The ancient Greek mathematician Archimedes is said to have taken a bath and figured out how to measure the volume of an object.
Good thinking
He may not be a world-renowned scientist, but Newcastle dad Blake Bennett had his own eureka moment a few years ago in a mundane place: the nappy aisle. Bennett went to a supermarket to get nappies for his daughter, Layla – who’s now 7 – but they’d sold out. So, he headed to a different store at the other end of his local shopping centre and discovered the nappies there were on sale.
“I bought three boxes and thought, ‘Hang on, I was about to buy these for far more elsewhere,’” says Bennett.
“I calculated that we saved about $45 and that’s how the idea started.”
The idea? A free website, Grocerize, that compares real-time prices for products at Coles and Woolworths. You can search for any item and see how much it costs at either supermarket, which together make up 65 per cent of the Australian grocery market. Grocerize believes it saves users an average of 28 per cent at the checkout.
