Paul’s secret ingredient ...nunchucks

A NEW detector device tells you if your home contains high levels of the radioactive gas radon – just by giving it a wave. The Wave by Airthings, about the size of a smoke detector, is attached to a wall or ceiling. When it senses a hand movement in front of it, it lights up in green, yellow or red to indicate good, raised or dangerously high levels. Radon is formed during decay of uranium, which occurs naturally in all rocks and soils, and can enter homes through cracks in the foundations. £157 airthings.com/wave

SCIENTISTS may have discovered why vegetarians often find themselves craving a juicy steak.

IT’S hard work pummelling dough – but Bake Off star Paul Hollywood, left, is rising to the challenge – by training with nunchucks, a martial-arts weapon made up of two sticks connected by a short rope or chain. Paul, 51, says: ‘I was into martial arts when I was younger and picked the nunchucks up again recently. I can use two pretty deftly. My arms are looking more toned now.’ However, the breadmaker says it has not come without injury, adding: ‘I hit my elbow and went numb from my elbow to my fingertips for a month. I forget I am not as young as I used to be!’
