Drill holes in a beer-pong table at the centers of where solo-cups would normally be placed. Attach air hoses to under each hole and connect to a single hose coming from the exhaust port of your central-vac or shop-vac.
Place ping-pong balls atop the holes and turn on the vacuum.
The balls will
now all hover above the table at a height determined by the amount of air flow diverted to the hose.
A ball has to stick to the double sided tape at the inside bottom of your thrown solo-cup to count or it is placed back in the air stream if knocked aside.

Won't the cup also be deflected by the airflow, making scoring impossible ? The open mouth of the cup is going to direct the airflow into the base, unless it is traveling normal to the jet, in which case the force will be on the outside, pushing it upward. |
|
| |
I'm not sure. I'm going to whip one up soon and we'll see. |
|
| |
In my head I see the momentum of the cup momentarily blocking airflow to the ball before it is deflected if thrown just right.
I might have to double-side tape the entire inside of the cup. |
|
| |
Spray glue instead of tape ? Quick, even coverage. |
|
| |
Nice. Maybe that rubbery stuff that gets sticky again when rinsed off. |
|
| |
We have a horrible suspicion that we know what substance you mean ... EEEEeeeeeeeewwww, too much information ... |
|
| |
Um... on a side note I stumbled on a pretty cool site because of what you just said. |

From link # 2:
"Different plastics are used to make Wall Walkers. They may be composed of an isoprene polymer (a synthetic
rubber), styrene-butadiene copolymer, or a poly (styrene -butylene- ethylene) copolymer along with tackifiers, and
coloring materials. In some cases, wall walkers glow in
the dark. This is due to the addition of a phosphorescent
zinc sulfide." |
|
| |
Not sure what you're referring to... and at this point I'm scared to Google. |
|
| |
So, uh... how 'bout dem Nicks? |
|
| |
We know it's rubbery and water makes it more sticky, so I'm guessing Borg have an aversion to the glue that comes on the back of postage stamps and you're supposed to lick. It's a reasonable aversion if you ask me. |

Failed Beernoulli experiment #1: |
|
| |
-Don't place the air-lines in series or the pressure diminishes for each hole. (hmmm it might be cool to have the balls hover at different elevations)
-Too small a hose diameter restricts air-flow so much that even though I left the far end of the hose open to prevent blowing the connections apart none of the air made it that far. |

Surely augmented reality, not alertnate reality? I don't even
know who Nate (or Nick, unless Saint Nick) is. |

[2 fries shy of a happy meal]; full-baking, nice!
A tip: use a plenum box (possibly with internal partial
baffles) then reasonably-shaped nozzles as your "table",
rather than trying to individually hose. Should give you a
more even air-flow.
[8th of 7], the airflow will affect the cup too, so you
would probably want to throw the cup mouth up(ish) at
the jet below the ball. Cup breaks airflow, allowing ball
to fall to cup, meanwhile airflow also pushes cup UP
towards ball.
Hardcore version: no tape, cup must land
upright (somewhere on table or floor nearby) with ball
inside... |

Any luck with the Coanda Tornado specs? |
|
| |
The frames are ready, but the lenses are still getting their final polishing. |
|
| |
[neut] is correct, a plenum is the way to go to ensure evenly distribution of flow/pressure. |
|
| |
Coanda Tornado - sorry [2 fries...], I had completely
forgotten I was going to play with that. I'll get on to it in the
new year. |
|
| |
No biggie.
It's not like it's the solution to industrial pollution and the energy crisis or anything. |
