Between relays, someone walks down and relights the candles. There are no " special effects". I describe how to do this " trick " in my article on Off-hand and Trick Shooting, which you can find under "Articles", towards the top of the index page to this forum, under Member Resources. Its not an easy trick, but its not that difficult, either.
If you are doing this kind of thing before an audience, you probably need to cut that final distance in half, so that the Audience, Kept behind the firing line, can see the candles clearly. Otherwise, they don't know what you are shooting at, until a candle flame goes out, and then, because they are looking at another candle, they missing seeing it snuffed!
Unless, of course, you do this kind of demonstration at NIGHT. Then it really gets fun! :grin: Night shooting requires the shooter learn how to use the candle light to find both his front and rear sights! He cleans and loads his gun in the dark. Then he has to align both sights with the candle and snuff the flame, without hitting the wick, or the candlestick.(DQ in most contests) :hmm: :thumbsup:
