To play rocks you need to
have:
Seperate
into two teams, make sure they are as close to even as possible.
Then put the whiffle balls in the hula hoops that are on opposite sides
of the field, or where ever you are playing. The extra hula hoops,
which are placed in random spots on each side of the dividing lines.
The whiffle balls are also divided evenly for the two teams. Once
all is fine and dandy with the game setup, its time to play the game.
The object of the game is to collect all the other teams whiffle balls.
To do this run over the dividing line, and try to get into the hula hoops
since the hula hoops are a safe zone. But you can only stay in the
hula hoops for five seconds. If you get tagged you are frozen until
someone from your team can tag you unfrozen, and walk you back to your
side. The main hula hoop is an unlimited free zone. You just
have to get there.
