Inventions Our countdown includes an umbrella holder that frees up your hands; a self-cooling aluminium can that means you donʼt have to keep your drinks in the fridge; a scooter that tows you to work using dog-power (while walking your pooch at the same time); a machine that boils an egg perfectly using halogen light power; a new approach to hair clips that stops the claws from digging into your head; golf tees that stay in the ground better, inspired by, of all things, the human tooth; and an ingenious idea by two Kenyans – a mobile phone charger that runs on pedal power!
