As a mom, I really like to have fun. But what I really like is fun I can eat! Ergo, gumdrop towers.
You'll need dry spaghetti noodles or toothpicks (better for school-aged children), a bag of gumdrops, and your imagination.
Using your supplies, build a tower with your child. Try different contests to see who can make the tallest, the roundest, the sturdiest ....
When you are done, eat the gumdrops :)
(P.S. Did I mention you should wash your hands BEFORE starting?)
