I build a water filter today. Bought a $37 Whirlpool filter from Lowes (Thanks Will!) and a few dollars of miscelanious parts.

The 3 gallon Rubbermaid cooler that I'm using as a carrier was found on the side of Mt Carmel Road, near my house. It was full of mud, but nothing a little B-Brite couldn't handle. Missing the lid, this seemed like a good use for it.
