Guy Pranks Drive Thru Workers With Floating Cup

This is the funniest thing I've seen in a while! this guy goes through drive thru's and orders food, no big deal, but it's what he does with the cup that sends workers into a frenzy! I have no idea how he does this, but the reactions are priceless!My favorite is the first person "Oh you see yo soda?! How you do that?! You serious??" hahahahaha!
