Here is a printable wristband that will get you free refills on drinks at Six Flags Discovery Kingdom. I made it by scanning my own wristband and then cleaned up the image quite a bit. The five-digit number on the left-hand side of the badge is fake. You have to have a big orange cup for them to refill in order for the wristband to be any use. I've included a picture of the cup and the original wristband. It might work with other Six Flags parks, too. Normally I wouldn't do something like this, but they just rip you off left and right at Six Flags.
