There are other similar magic effects where a lit candle is passed through a number of silks threaded through a tube. This version is exceptionally clean and convincing, with the added advantage that all the apparatus can be freely handled by a spectator and thoroughly examined. Performer displays a pair of nesting tubes, with two pairs of holes across each tube, and a pair of silks. The silks are pushed through the holes, criss-crossing each other, and apparently fill the entire inside of the inner tube. A lit candle is now passed through the tube, apparently going right through the silks. The silks are removed and shown to be completely unharmed, and all the apparatus can be immediately handed over to a spectator for examination. This comes complete with two silks and tubes and detailed instructions. You can use any candle.
