Resembling a sort of large waffle-press, the BorgCo
snow frisbee mould is simplicity itself to use.
Just fill the mould cavity with a generous amount of
fresh snow, and press the handles together until
they lock. After a few seconds, release the clip,
open the mould, and remove the aerodynamic
disc
of compressed ice crystals.
Heavier than a regular plastic frisbee, and thus
capable of inflicting disabling injuries on the enemy
at ranges
beyond that of a regular snowball, even one with a
rock in the centre.
Hours of violent fun for all the family.
Versions under development include a "clay
pigeon" mould, and a "discus" design.

I think you're going to have issues, [8th]. |
|
| |
Well, let me be more precise. I think you're going to
have issues related to this invention. Conventional
Frisbee throwing places a very large centripugal load
on the Frisbee during the launch phase. I don't think
a compressed snow Frisbee is going to survive the
launch. |
|
| |
If you compress to the point of regelation, creating a
solid ice Frisbee, strength will be higher but so will
mass, and hence the load on the rim during launch. |
|
| |
You might to better to make a sort of rugby-ball
shape that can be launched, with spin, in the manner
favoured by players of American "football". |
|
| |
Rimless ice-discus with sandpaper-gloves. Snowball fights may never be the same. Very nice, 8th. Somebody remind me in a few months. |
|
| |
I like the visual. Too bad if they fall apart before thrown. I
still like the visual of flying spheres of snow. The rock part is
for throwing harmlessly at barns and bridges and such. Not
people. A definite plus. + |

//ice-discus// Now, that might work. A discus is
thrown with inward pressure of the fingers against
the rim (completely the opposite to the way a
Frisbee is thrown), so it only has to support the
centripugal force of its own rotation in flight. |
|
| |
The Inupiat sometimes kill* fish and birds by throwing
makeshift "ice spears" at them. These "spears" are
actually very short and fat (closer in shape to a rugby
ball, but a bit longer and pointier). They're thrown in
such a way as to spin them, which means they can be
thrown into the water without deflecting too much. |
|
| |
A mold ? Like a trash can lid ? |
|
| |
That's kind, but I already have one. |
|
| |
Yes, but it's a very selfless offer; after all, if he gives his lid away, when
it rains he'll get terribly wet. |
|
| |
Well, just add sawdust or some other, even more fibrous material into the mix to reinforce it. It should be relatively trivial to create an ice composite that is capable of withstanding the centripetal forces, and likely some of the impact forces as well. |
|
| |
Ah, the Pykrete Frisbee … and so another
arms race begins … |
|
| |
Surely a lime-based binder, with an appropriate aggregate would also contribute to structural integrity? |
