I purchased these "star" candles on my shopping excursion on Wednesday....they have a battery tea lite molded into them. When you sit them in water they light up and when you take them out...they go off. How cool is that!!!! I added some Lemon Balm to some water in a bowl and added the star light candle - I think I should add some flower petals too....how pretty and what a nice centerpiece for your table. A customer already wants some for her fish pond....I need to order more!!!
