tennis ball team building

The challenge of this game was to see which group was the fastest to pass the ball around to every person in the group.  For our first trial we came up with two ideas, the first everyone formed a circle and in alternate order one person put one hand facing up and the next person facing down then handed the ball to from person to person.  The second we formed a circle and put all our hands in the middle facing up then just rolledd the ball around like it was on a track.  After the two groups first competition we added the contsriant that only one person may touch the ball at a time.  So my group came up with rolling the ball down our hands like a ramp or hill.  The next constriant we added was that everyone had to be an arms length apart so my group just formed a circle and just passed the ball around.  Our plans for these constriants did work out well but we just weren't fast enough to beat the other group. So next time what I would have done differently would be make the incline the ball rolled down on the first contriant steeper and for the second constriant just try to pass the ball around faster.  What   i would have kept the same is our second idea for getting the ball around with no constriants.
