Many years ago, I had the idea of a shark aquarium tank. The idea was to fill the tank with fog, like it were murky water. Also a light source above with a water effect. Their also might be some deep sea creatures inside as well.

The audience would see a vague profile of a shark swimming by in the distance. That could be a cut-out, or a rear-screen video projection. Then after it was no longer visible, a shark would come straight towards them, and even burst through the tank glass panel.

Never got to implement it.

I also recall a version, where the audience is walking through a clear tunnel. The fake aquarium is perhaps a bit leaky and rusty.

Ideally to get into the tunnel under the water, they have to go down some steps or a ramp. If the water tank illusion is convincing, that would increase the apparent danger of the tunnel collapsing and them being immersed in the water with the shark. Though you would need to have perhaps a house with a daylight basement to have a yard that would make this viable.
