yoo legend
this is what we do at ssd..
it's called the freestyle challenge
get a few kids. at the beginning they think this is easy but they will see haha
you do something and they have to do the same thing and catch it in there hands at the end..
soo you do foot-knee-catch the ball in the hands and they have to do the same.
if someone doesn't catch it or faill the challenge then they have to sit.
the next challenge has to be a bit harder so something like this foot-knee-shoulder and each time try to make it harder and at the end there is 1 winner.
goodluck!
if you don't understand it let me know man!
