Sparkler Bomb Materials: * 12-20 sparklers * duct tape Procedure: * Bunch sparlers together so that all ends are even, except one sticking out of the middle of the pack about 2". * Cover the whole thing with a lot of duct tape, leaving the middle sparkler bare as a fuse. * After lighting the end sparkler, it burns to the others, all igniting at the same time, causing a decent explosion. It really works better than it sounds. Maybe you already know about it, but we'd just thought we'd check.
