why dont you do a knee grabb and dance your butt over to the water bottle pretend your thirsty, and pretend to take a drink, so wipe some sweat off of your brow take a swig of the bottle (fake like) then pop the ball out of the knees and do a foot stall then flip the bottle and get the ball on the bottom of the bottle and then place it on the fore head.
you must practice this alot because the balance as you put it on your head is difficult.
also note you look sloppy by using your hands with the ball in order to place the bottle on your head.
this is how i roll and crows dig it. they get a laugh that i stopped and was thristy so i drank. its always funny.
try smaller can similar to a red bull can and then untie your shoe and put it up on top of the ball that already on the can that ones sick to and then you can take the shoe off the top and let the can drop out forwards as you catch the ball on your neck and take a bow. its my perfect ending.
hope this helps good luck..
ps pleas dont use your hands to get teh ball on the top it lookds terrible and the judges will call you on it i guarantee it.
Judges comment "oh isnt this soccer? whyd you use your hands?, pure slops"
