This is an installation currently in Covent Garden.
‘The idea is based on human touch – making a connection – is what helps to power the tree’s lights. KISS is activated when two people hold the mistletoe under the tree and kiss. The electricity of their touch spectacularly lights up 50,000 red and white LED lights, creating a sensational light installation.’
‘we are also encouraging visitors to donate a minimum of £1 for every kiss they share under the Christmas tree’ in aid of the Princes Trust.
Sounds like a good energy saving idea as well as a bit of fun.
