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 ;)

What a fun rainy day activity!! On a tray, place a pile of baking soda. Mix vinegar + a few drops of food coloring in a cup. Give the kids an eyedropper. Have them fill it with vinegar, squeeze onto the baking soda and watch mini volcanoes erupt!
A great way for kids to watch a seed grow. Lots of other kid-friendly gardening ideas, too.
