Brew your own potion for new HBP YouTube contest

Warner Brothers and YouTube have kicked off a very cool new Half-Blood Prince potion brewing contest!

There are two ways to go about making your potion. One way involves printing out a potion marker which – when held up to the camera – will add a 3D cauldron to your video. The cauldron moves around the screen as you move the paper around in front of the camera!

The other way to make your potion is much simpler. Simply record a video of yourself making a potion!
