Gizmodo reader Brad Kremer sent this beautiful home movie, shot at 2,564 frames per second with a Phantom Flex, Zeiss super speed glass, Canon 5DMKII and Canon L series glass. Total: $300,000 to shoot what's probably the coolest water balloon battle ever filmed. Worth every cent and second.

"As summer comes to an end and Autumn begins, kids go back to school and dream of warm days filled with laughter and joy," Brad says.

Sigh. It feels so far away now. [Thanks Brad!]
