    I voted for Lisa because the explanation gives meaning to the phrase: "stand back"

    Me too. When I was doing compressive-strength tests of mortar and concrete, those test-cylinders would sometimes practically explode. I imagine that deflection-tests on beams could produce shrapnel, too.

    This is ongoing research, they hope to find things in EEG that will help in early dyslexia diagnosis.

    Actually the capacitor/inductor bank in my picture, when fully charged and operational, would also qualify to be included in the "stand back" advice. :)

    It is typically charged up to 43 kV, and will be shielded behind a thick G10 board and interlocked inside a cabinet. Whenever the cabinet door is opened, a dump switch will close to ground all the capacitors. Still, one has to use a grounding stick and touch every single component in the cabinet before maintenance/repair work can commence.

    Without all these safeguards, you literally will get a shock from even a couple of feet away.

    And people say physics work is boring......

    :)

    Very odd Glondor. You've not already voted have you? One name will appear in italics if you have. Post a note here if you still can't vote when you read this.
    Is anyone else having problems?
