Glow sticks in the pool, great for night swimming! Not sure this would be the best idea for a big in ground pool (would probably take a couple hundred sticks), but would definitely be cool in a kid pool or an above ground pool!
The Best Fruit Salad Recipe: cup of powdered sugar 2 tsp of vanilla. Though, I would minus the powdered sugar and just do vanilla extract. The fruit has natural sugars/ juices that would make taste sweet enough.
