It's America's 238th birthday! I can tell because there are fireworks vendors populating every possible parking lot, and things benignly exploding with beautiful trailing sparks overhead. For American fireworks aficionados who are also geology buffs, this is the best time o' year. But no matter where you are in the world, you can enjoy learning about the geology of fireworks, and I'm sure there will be some brilliant lights burning in the sky soon!
