At the Park

Next time you're doing the grocery shopping, grab a bag of balloons off the shelf and throw them in your cart. When you get to the car, put them in the glove box. Next time you stop at a park to play, pull out the bag of balloons. You will instantly be the coolest mom on the playground (according to anyone under 3' tall, anyway).

If you're feeling brave, try it with bubbles, although it has more of a Pied Piper effect...
