A great tip, from a great blog. Kevin Kelly’s Cool Tools offers up a reader suggestion every day for a tool that is, well, really cool. Preference is given to tools that can be put to use for something other than their original intention—like using a rubber band as a photographic device. More specifically, you can use that rubber band to remove stuck filters from the front of your lens. It’s a great idea—one of those "why didn’t I think of that before" moments. Read all about it at Cool Tools, and stick around to check out all the other great tool ideas—like plastic banana keepers and custom igloo builders and bright lights just for your hands!
