Million Farad Capacitors
When I was a kid, my Dad told me to fear large capacitors. He was protecting me from danger while I was disassembling an old CRT. According to the Navy Basic Electronics manual, the resistance of the human body is 300 ohms when soaking wet (worst case), and 100mA of current through the heart can kill you.
