Re: OT: Repeatably lobbing "projectiles"

Engineering is not just about solving problems but, rather, about identifying
the problem to be solved.

We have been told the range is about 20ft (but no accuracy limits) and
there have been hints about what the projectile must not do (bounce or
injure bystanders) but the main constraints on the projectile were not
known at the outset and this was mainly what was making the problem more
difficult than it needed to be.


The sorts of properties that make a huge difference to the design are:

Rigid , flexible, floppy or completely shapeless like a bag of water?
If fairly rigid: spherical, cylindrical or some other shape?
Approximate range of mass?
Homogenous or made from bits of widely differing density?

There is a vast difference between trying project a
quarter-inch-diameter lead ball 20ft and trying to do the same with a
bucketfull of cows guts.
