Underwater Pumpkin Carving Show is a fan-favorite Oddtober tradition at the Tennessee Aquarium in Chattanooga, where divers carve pumpkins beneath the water. It's a quirky, one-of-a-kind spin on Halloween fun, and the aquarium's big tanks make it a show you won't see anywhere else. Part of the aquarium's month-long Oddtober celebration, it's a great pick for a sunny October afternoon. Bring the family, grab a spot to watch and enjoy the spooky-season surprise.
