iv got a candle at home and when the wick is lit the candle changes differant colours red.blue green ect.how does it work because curiosity means im close to chopping it in half to see whats in it????
lol ... Have a look at this site - their candles use an optical fibre along the wick which activates coloured LED bulbs according to their blurb. They don't say what happens to the bulbs when the flame gets to their level though !
