general idea: A pocket sized electromagnet on a braided cord for all kinds of activities such as removing keys from a storm drain (yes i know they are brass but the rings are steel!) all of this fits in a D.O. can. Very simple horseshoe shaped electromagnet (double the gripping power) suspended from a cord made of braided: motor wire (enameled) and fishing line for added strength.
PLEASE READ ON!
1 d.o. can
plenty of enameled motor wire and fishing line
1 battery clip of preferred battery type (9v seems to work best)
1 small bend iron object to wrap the wire around (cut one side off a chain link)
1 toggle switch
a short length of pex and something to cut it with
supper glue or a glue that works well with plastic
alcohol to clean the labels off the pex
craft foam so it doesn't rattle in your pocket
