Well, did you think about the children who are starving because you selfishly hide all that valuable personal info?

It is just a decoration. It has no practical function. Trying to use it under water would be a major hurdle and likely very dangerous.

Speaking of which, the microwave walls are made from steel, so there is always a lot of it in the microwave, whenever you turn it on. Oh, horror!

I mean, your neighbors will have to call, because you will be either dead or very busy coughing up what is left of your lungs.

Right. Buckets of liquid bromine in a gizmo at home, what could possibly gone wrong?
