Flame-free Jack o' Lantern: use Christmas lights!
Have trouble keeping your Halloween jack o' lantern lit? Tired of burning pumpkin?
Take a bundle of 25 or 50 christmas tree lights and put them in a clear baggie so they don't get pumpkin goo on them, throw the bag inside, cut a hole in the back for the plug to go through and, viola, instant guaranteed light! They never go out and are much brighter than a candle.
I recommend using LED lights which don't get hot.
