I have this First Aid Kit that I keep in the car. The kids have recently found it, and they are completely enthralled.
There are pages of stuff in here, neatly stacked in pockets. Things like scissors, a tweezer, an eye patch, re-useable ice pack, bandages of all kinds. Sunscreen, lip balm, instructions on how to help someone who is choking. It's completely fascinating. It's like a hospital in a zippered bag.
My "I Wonder Why" is this: Is it an "Emergency" if the band-aid is only this big??
