I think rules would be the detriment of this contest. Let the looseness of the rules be the rules since grading ...will be awarded based on distance thrown, style and whimsy.
Leave it to each team to self define "style" and "whimsy."

In reply to ansonivan:
dude, patent this idea now and set up a server. make you some money! like, it costs $5 to upload your video but the weekly winner gets $100 or something like that.
you can thank me later, when you have a show on Discovery.
aaand, GO!
I think it has television potential
The bow powered catapult was not particularly impressive, user friendly or safe. The longest shot was around 15 yards, I can throw farther than that without the risk of having my ear ripped off by a speeding lacrosse stick. Range improved after moving the release hook closer to the basket end of the stick, this also made the thing incredibly difficult to use. The catapult arm and release hook will need some work in order to harness the full potential of the ski power.

Wow, that looked incredibly dangerous in that 2nd vid! 
This is gonna be awesome!
I didn't get to participate today, will there be one next weekend???
EPIC.
Well, maybe not epic but this certainly sets the stage for good humor and fun viewing/activity.
Great shot hitting the pole (ding.)
I agree with Pete above, the danger is the awesomeness!
holy carp that DING! was perfect! ahah!
I'm all for doing this again, just need to come up with another objective. I think setting a one word theme rather than a specific objective could lead to more varied and interesting creations. For example setting the theme to "Flight" could lead participants to build anything from an aircraft to a catapult to a fat guy dressed in flying gear stitched together from a thrift-sourced leather sofa.
Setting the objective or theme by Wednesday afternoon each week would give more time for people to get involved.
Why not making something that can transport a guy without him having to pump up the power?
Beaterworld, that could working but if only uses half rotate engine.
Actually, I was thinking that you can only use potential-kinetic energy- and no fuel

I can deliver you that.
Its called a free fall. We will walk you up a building, then we will walk down, you will be transported without having to pump up the power.
err, it's actually across a parking lot.
You never stipulated that. I win.

oh, and getting him up to 40 mph. I can do that, although I might need a hill...

Depending on your weight and physical size I can get you to about 125 ;)
The maximum speed of a person falling from an airplane is limited by air resistance (drag). You may have seen that skydivers extend their arms and legs outward. This increases the air resistance, and results in the lowest possible free-fall speed. If they retract their arms and legs, they fall faster. You will experience air resistance (drag) if you carefully put your hand out of a fast moving or train. The drag is greatest if you have your hand open at 90 degrees to the direction of movement i.e. maximum surface area. Drag force is directly proportional to the surface area resisting the flow, the viscosity (“thickness”) of the medium (air in this case) and proportional to the square of the velocity of falling. Drag force also depends on the shape of the falling object. If it is streamlined, drag will be low. If the object has sharp edges, it will have higher drag. This is the physics of aerodynamics, including turbulent flow and laminar flow of air around objects. Vehicle shapes are tested in a wind tunnel to improve their aerodynamics, reduce drag and so improve performance factors such as speed and fuel efficiency. As a skydivers’ speed increases, drag force due to air resistance increases, until it balances the downward force of gravity due to the person's weight. At that point, the acceleration stops, since the forces are in balance, and the skydiver will keep the same speed, called terminal velocity. For a free-falling skydiver this is about 200 km/h (125 mph). Read about ”Adventures in Skydiving” at the SEED web site.
