Lava lamps and fish........
Both are transfixing if you stop and watch them. The cool thing about lava lamps is that they don't have to be fed!!!!
I pretty much did the same thing yesterday, only my stops were all at antique shops. I found my wife 5 little real old blue bottles to add to her collection. I'm going to give them to her for valentines day. I didn't find anything I couldn't live without

, but at least I found something unique for Valentines day, and didn't wait till the last minute to do it !!! (for a change)
