How to Make Clear Coffee

Yesterday evening I washed out the coffeepot and put everything back together. Then I got it all ready to make coffee in the morning, so all hubby had to do was turn it on. Well this morning he turned it on and after about 4 minutes he said, this is the clearest coffee I've ever seen. Even though I could have sworn I'd put coffee in the filter there was none there, personally I think Aliens took it. ;-)
