Bounce dirt from your clothes
These weird, spaceship-looking, green balls are billed as detergent substitutes. Put them into your washing machine with your dirty clothes, and they supposedly produce ionised oxygen, naturally activating nearby water molecules. This, according to their maker, enables the balls, priced at approximately $US70 for a set of three, to penetrate deep into clothing fibres and lift dirt away. Eco Balls
promise to be chemical-free and environmentally friendly, and the maker says that one set will last for 1000 washes, which would make them less expensive regular detergent.
