Would some sort of lamp without a shade behind a red/orange cloth screen made to look like flames work for this (safely without the bulb touching the cloth)? Using the PP idea of a surge protetor and a switch to turn the light on suddenly may have the same effect. Maybe having a small fan also turn on and blow red/orange cloth strips so it looks like flames? Just ideas (and I don't claim to be creative, lol!).
Our VBS is 9 to 12 a.m. next week and I work all mornings so have to help other ways. Our theme this year is "Camp EDGE" and i've helped find some things to make the fellowship hall look like a camp (small 2 person tents, artificial christmas trees of various sizes to look like a forest, some larger rocks, firewood, camping gear, etc.)
DH is home for the summer so I signed him up instead, LOL. He is in charge of games and recreation with another dad and he is excited! We cap our week off with church at a big park (praise band, kids sing the VBS songs) and a potluck picnic.
