DEVICE KILLS MUSIC FOR STREET-DANCING GRANNIES

It is normally young people who drive retirees mad by blaring loud music at all hours. But in China, the youth are so fed up with street-dancing grandmothers they're buying “stun guns” that can sabotage loudspeakers from 50 metres.

Since the 1960s, older women have gathered in public to dance to loud music, usually early or late in the day. Their use of rare public spaces, combined with the noise pollution, often results in standoffs with younger people. The women have been known to break on to basketball courts and football pitches and stop ongoing matches so they can dance.

A look at products sold on Weibo by the South China Morning Post found dozens of “anti-square-dancing devices.”
