This one is best for teams of 2, but you could do it individually
Inside probably
Put team members at opposite ends of a room with lines they have to throw from, put a slice of bread with peanut butter on it between them, either on something or just on the floor (PB side up!). Players have to bounce he ball so that it hits the floor once and then hits the bread and sticks. If they miss it will bounce to their team mate who will retrive it and then make an attempt. First team to land the ball wins.
Scoring is, as always, completely arbitrary, you can award only the fastest team or award points for anyone who got close. Decide how you wish based on the number of players.
You don't have to use peanut butter or similar sticky food stuff (it is a slight waste of food, I doubt anyone will volunteer to eat it afterwards), you could just have an empty can, or similar, as the target. You could put something in the bottom of the container to control bounce-outs.
Pre- or post-bounce requirements are optional.
Teams can go one at a time or if you have the space and like chaos give them all different coloured balls and let them all go at it at once.
