confetti and the cans into projectiles."

Caps can be dangerous alright. I remember an incident from a military class on HV (radar) power
supplies. The class clown got knocked on his ass by touching the wrong part of the (experiment)
power supply. As he was picking himself up off the floor and when he cleared the edge of the
workbench, a cap blew and he got slapped between the eyes with part of the cap's aluminum case.
Down he went, again.
