Wanna convince your kids there REALLY IS A SANTA CLAUS?? I know how. I've done it. I had my son believing until he was 13 - I so completely convinced him. Here's how step by step. What you need: 1, Two walkie talkies. Don't use a phone - or cheapo $10 toy walkie talkies. 2, A friend with a car that has a car stereo. 3, A sound effect of wind that will play on your friends car stereo. That's it.
