That’s kind of fucked up if there’s not an indication that it’s a replica. Akin to yelling fire in a theater if someone used one of them maliciously.

Perhaps it could be kind of neat as a curio if it’s a highly engineered/beautiful work of art (that is maybe too expensive to use for malicious ‘jokes’). But I’d still want it to have some sort of indication that folks aren’t getting dosed/they don’t have to trigger a response by your local atomic energy officials.

Editing to add that before I picked Krakatoa (fingers crossed on my inability to predict natural disasters), I actually searched for “disasters with no death toll” to use as an example for a potential model without much success. It is in poor taste and my comments are definitely parody.
