This effect started out as a basic explosion experiment for something completely unrelated to water. As I continued to iterate, however, I realized that I could mockup a fairly decent underwater explosion (implosion?) with a few additional elements. The biggest challenge was creating a convincing vacuum-like effect as the pressure collapses the canister.

Definitely not photo-real but I'd be curious to know what you think!

I created all of the visual elements within After Effects using Particular, CC Cylinder, and a bunch of fractal noise.
The sound effect was kindly sourced from and the User known as DigiFishMusic.
