is to get a roman candle, hold it and light it. Every few seconds you get another shot.... either that or get a really big rocket and make sure it's stuck in the ground securely enough it can't take off... of course, with that one, you retire at a rate of knots, since it's amazing how big the blast radius on those things is...
*grins wryly and recalls the resulting smell of burned hair*
What's also really fun, but very stupid, is combining fireworks and barbecues... or the old trick of rolling someone a cigarette with a match head in it... or ammonium tri-iodide on anything, but doorknobs in particular... or anything even vaguely flammable with me around... |
