ThinkGeek says 'All you have to do is press the master on/off switch on the bottom, and these candles will turn on and off with just a puff at the "flame." From the proper distance and height, these candles will fool everyone into thinking they are the real thing; they are a fantastic way to put candles where it is too dangerous to have open flames'. Of course no drippy wax that needs t be scrubbed clean from everywhere either. The LED candles have a waxy coating and look just like normal candles. Available in sizes from 4" / 5" and 6" tall, the candles run on AA batteries with upto 300 hours of 'burning' before you need to change the cells.

You could even let the young ones have them since you always were concerned about accidents if they had fire in their room. Burn the worries with the LED candles.
