How much fun can you have with 4 kids and a pack of yellow Post It's? The answer I've discovered is loads.
Write a name, thing, object on the Post It and stick it to the forehead of a child and get them to guess who or what they are with 20 questions.
So far my Niece has been a Do-nut, a Monorail and La La from the Teletubbies. My Nephew has been a Submarine, Jelly and Dash from the Incredibles, 6 year old has been a Hotdog, Shaggy from Scooby Doo and a Bike and 10 year old has been a Car, Glinda The Good Fairy and a Cheesecake.
Best of all...they've all been amused and quiet for the last hour, they've laughed and learned something during the course of their questions and it ain't cost me a penny! Where else can you get away with calling your Niece a Do-Nut or hearing your Nephew ask if he'd eat himself if he could?
