made a tool to grab metal out of bottom of big dumpsters

I got some old thin chain and have a big magnet . I bent chain and put bolt thru braket of magnet. Now i can reach a good 50 foot to bottom of big trash cans i can not get in and out of. You know for those hard to reach areas.magnet was from some desk sighn you know you stretch it across a walk way to keep customers back like at a bank. I will add bigger stronger magnet later if too weak. The one i have now sticks to my big rolling tool box and can move it.
