First, real magic. OK, not real, but close to it. The new wands in the park are interactive, so at 25 locations in Diagon Alley, you can wave your wand, say a spell, and perform actual magic. You can make a feather rise up with Wingardium Leviosa, turn the drinking fountain on with Aguamenti, and even perform some dark magic in Knockturn Alley.
