First, I got Puck U from the talk show guys at 550 AM in San Antonio.

I propose that in a large lecture classroom and a small one, a Red Suited shooter with a Sims gun attack the class which has hockey pucks. I propose pocket carry for the pucks. Rules would be that if you are hit with the Sims round (protective head gear of course for the 'students') you are out. A protected referee will film the hits on the shooter and call it if enough pucks impact.
The large lecture room should have significant distance between students and attacker with perhaps 50 students. The small one, close in class with maybe 15 to 20 kids.
I am an experimentalist.
