I had already heard about the negative effects of licking 9V batteries so I felt that I was ahead of the curve. Then I took a small DC electric motor and had wires running off both terminals with the insulation stripped off the ends, and inserted the two ends into a wall socket thinking I could really make this thing spin. Blew it out of my hand and 3 ft. away. The lights went off for a split second but it didn't blow a fuse. That was when I started learning about different types of electric power.
