Finally we can put this argument to bed

A Chinese start-up has invented a long-distance kissing machine that transmits users’ kiss data collected through motion sensors hidden in silicon lips, which simultaneously move when replaying kisses received.

MUA – named after the sound people commonly make when blowing a kiss – also captures and replays sound and warms up slightly during kissing, making the experience more authentic, said Beijing-based Siweifushe.

Users can even download kissing data submitted via an accompanying app by other users. The invention was inspired by lockdown isolation. At their most severe, China’s lockdowns saw authorities forbid residents to leave their apartments for months on end.
