Far better to just dump a bottle of water on the masks. They won't know if something was in the water, so the won't be able to use them. It'll cost them money and time to deal with while costing you almost no time or money. Wear a mask while doing it so you won't ~~be identified~~catch covid. Remember our enemies have much better funding and don't need to work (free gibs). I bet this bitch is on a free ride because of minority and scholarships while also haven't no homework in her "classes". People need to start thinking in asymmetric warfare tactics.
