Liquid drum set

[Rust]

So I was at a different music store (the kind that sells instruments) because my normal spot had been hit by a tornado. Walked in and walked past a drum kit set up front, then stopped and went WTF and then turned around and looked closer. The "drums", an exact replica of a full double kick set were in fact aquariums, the kicks and toms salt water, snares fresh water. Exact replicas.

So I'm thinking those glass speaker enclosures.....
