The good folks at HTD arrange 6,000 matches into a tight rectangle. Then they light a single match in the corner. That one ignites, then spreads to its fire to its neighbors. The wave of flame sounds like a violent wind.
The fire continues, gradually burning into ashes. It's an almost meditative experience. The 6,000 matches are your worried for the day. The flame is your peace within. Or an entire gallon of ice cream--really, whatever works for you.
