This website has tons of cute babyshower ideas!
Place milk in shallow dish- add drops of food coloring. Now grab a *magic* toothpick. What? You don’t know where to buy magic toothpicks?? Just dip the end in dish soap & touch the milk with it. Colors instantly shoot out at lightning speed creating a wake of rainbows! Try dipping the toothpick in the color first and then the milk and you’ll make rings. Do not drink the milk ;)
