I think these sound kinda fun, so I thought I'd share.

Paper Plate Frisbee Discus (outdoor)
The paper plates used in this event, are standard paper plates, preferably without the laminated or plastic coating. They are cardboard, with crinkled edges, round and about 25cm in diameter.

Contestants stand with their feet behind a line. They flip, throw, spin, toss the plates across an open space. The distance measured is where the plate ENDS UP (not necessarily where it lands) to the throwing line. Plates cannot be torn, bent, folded or changed in any other way.

Plastic straw Javelin
Plastic straws, about 25cm in length, and 4mm in diameter are used. Try to find ones that don't have that bendy bit in the middle.
Contestants stand with their feet behind a line. They flip, throw, spin, toss the straws across an open space. The distance measured is where the straw ENDS UP (not necessarily where it lands) to the throwing line. Straws cannot be torn, bent, folded or changed in any other way. Note especially that nothing can be put inside the straw before it is thrown.

Cotton Ball Shotput
This is a new event, so if you do it, please tell me the size of the coton wool ball.
Contestants stand with their feet behind a line. They flip, throw, spin, toss the cotton wool balls across an open space. The distance measured is where the ball ENDS UP (not necessarily where it lands) to the throwing line. Cotton Wool balls cannot be torn, bent, folded or changed in any other way, and cannot have anything added to them, especially not water or any other liquid.

Standing Jump
Contestants stand behind a line on the ground. Both feet must be behind the line. Without moving their feet before take off, jump as far forward as possible (i.e. no run up, steps, or any other foot movement before the jump). The distance from the line to the closest point that ANY part of their body touches the ground is the distance jumped.

You may wish to break this age and gender groups to be really fair to everyone.
