1. A man on the radio explaining an invention that makes supermarkets sing. He's been colourblind since birth and cunning scientists have togged him out with a box that plays a different tone for each colour. 'The fruit and vegetable section of the supermarket is very noisy,' he said.
2. Opening a new tin of coffee. I love the tearing metal and the hiss as the pressure equalises and the smell that rises up.
3. Bacon that goes crispy and makes proper fat instead of weird white foamy stuff.
