Don't plug an electric 12 volt heater motor with a squirell cage fan into 110 volts. The fan will explode and send shrapnel everywhere, 11 years old. As an added note to this, I was in the hospital a few years later(16 yrs old) having knee surgery, there was a kid about 11 in the bed next to me missing a hand, any guess how he lost it? Yup, did the same stupid stunt as I did, I just lucked out.
