Refilling beverage cans See reader questions & answers on this topic! - Help others by sharing your knowledge Safety * Always use professionally made pyrotechnics, don't improvise them (not even flashpowder) * Use a commercial control box, with a removable safety key * Never smoke while handling pyrotechnics * Unpack the pyro in a safe place, away from anything flammable * Store pyro in it's packaging until you use it * Never put pyro in your pockets * Turn the control box off and take the key with you while loading pyro * If the pyro is a cartridge designed to be used in a pod, use a real pod, don't just twist wire to the terminals * Ensure that each pyro position can be clearly seen from the control position * Never fire a pyro effect unless you can clearly see the area is clear of cast and crew * Always wear safety goggles or a face shield when loading pyro. * Always clean your flashpots before loading them. (reduces "shrapnel") * Never try re-firing a dud. Soak it in water and destroy it by tearing it to pieces. * Never dispose of destroyed pyro duds in the trash; use a "safe can". * Never fire pyro over an audience. Two manufacturers of theatrical pyro are Le Maitre ( http://www.lemaitrefx.com/ ) and Jem (no web site, but pictures and descriptions at http://www.midnight-design.ltd.uk/spyro.htm ). Le Maitre's PyroFlash system and Jem's Stage FX are similar in many respects. They have a control box, a number of 'pods' connected by cable to the control box and a range of pyro cartridges that can be plugged into the pods. Effects cartridges include * Flash - a bright white or coloured flash and puff of smoke * Starburst - similar to the flash, with a spray of silver or gold stars * Smoke - Dense white or coloured smoke, burning for tens of seconds * Fire - intense coloured flames and white smoke * Whistler - Loud screaming noise * Glitter or confetti - Loud bang and a spray of confetti or glitter Other effects include gerbs, maroons and confetti cannon. Gerbs spray white or gold stars in a 30+ foot jet for a few tens of seconds. These are spectacular for outdoor performances, but think very carefully before trying to use them indoors - they spray white-hot fragments a long way. Maroons come in a range of sizes. The smallest ones make a very loud bang. The larger ones are very, very loud. Maroons should only ever be fired in a bomb tank - this is a heavy metal tank with an open top covered with a metal mesh. When fired they will throw fragments out of the top of the tank. Always put up clear warning notices near the bomb tank, ensure everyone knows you're using maroons and ensure no-one is near the tank when you fire the maroon. A confetti cannon is a short cannon which uses a maroon to fire confetti (or glitter or fireproofed leaves or...) into a huge swirling cloud.
