On Christmas Eve, Santa Claus magically manages to get to the home of every good little boy and girl in the world to bring them presents and eat their cookies and milk.

Amazing!

But what do you say when a child asks you how he manages to do it?

Thankfully, the days of answering "uh, magic?" are over because technology is here to save the day.

Both the North American Aerospace Defense Command (NORAD) and Google have Santa radars that track old Saint Nick's annual round-the-world flight.

NORAD has been tracking Santa for over 60 years and their website and app definitely don't disappoint.

Visitors to their website, noradsanta.org, will find movies, games, music and more. You can also call 1-877-HI-NORAD on December 24 for up-to-the-minute Santa data.

Google has been in the Santa tracking game for 12 years. Theirincludes Santa’s Village with a countdown clock, learning opportunities, activities, and games featuring penguins and dancing elves.

NORAD and Google will allow users to watch Santa in real-time as he leaves the North Pole and sets out on his present delivering journey.

But it should be noted, when he visits your house, you should be in bed. He'll know if you're not.
