~ INDIANA JONES & THE EARTHBALL OF DOOM! ~
Divide the group into ¼ (inner circle) and ¾ (outer circle) sub-groups.  The inner circle participants stand with their backs together facing out.  The outer circle participants form a circle facing the inner circle.  Place one ball and one runner on the track between the two circles.  Give the runner a 4 foot lead.  The facilitator holds the ball and no one is allowed to get behind to push start it.  On “Go” everyone starts pushing the ball towards runner with their hands as the runner tries to run away.  If participant is fast enough and tags the ball, they win.  If the ball “tags” them (or is just about to tag them), the ball wins.  
SAFETY:  Do a test roll around with the ball to make sure the two circles are spaced far enough apart.  All participants must only use their hands to propel ball forward.  No kicking or pushing with feet as the runner could be tripped.  Call “Tagged” before the runner is actually tagged by the Earthball to avoid the runner being flattened.  Inner circle participants are often tempted to step out to see the ball coming but that could lead to collisions with runner.

~ EARTHBALL TOSS ~
Divide the group into two teams.  Each team is given a small tarp.  Each group positions members around 3 sides of the tarp and hold it taunt.  One team lowers the tarp and the ball is placed on their tarp. The team must work together to toss the ball over to the other tarp.  (Sometimes the ball bounces in between and then onto the other tarp. Ok, by me!)  
With two balls and two tarps, each team could compete to see which team could loft it in the air the highest.

~ HUMAN FOOSBALL ~
Equipment:  Cageball, 6-8 retired climbing ropes, open space
Divide the group into 2 teams, 6-8 people per team.  Each pair will have a rope and stand across the field from each other (like jump rope) Pairs from team A will alternate with pairs from team B.

The cage ball is rolled into the middle from the sidelines and the teams swing their respective ropes to “catch” the cage ball and toss it towards the opponent’s goal line.  Each pair must remain in their areas (cannot run up and down the field) Once the ball is thrown past the goal line, a point is scored.   SAFETY:  Watch out for swinging ropes as they can catch an eye or whip someone.  Also gloves may be advised if playing for extended periods to prevent blisters.
