If you have a tabletop fountain, try adding a few drops of vanilla, or mint to the water. The aroma will soon fill the room. Experiment and use the scents you like best.
Great idea! And I love your comment about regretting never getting a chemistry set -- me to! I begged for one from the sears catalog every christmas from the time I was 4 til I was 13, but I guess Mama and Daddy were smarter than me, cause our house never got blown up! LOL. Oh well.....
