This can easily-peasily be enacted at your local beer garden with of no more specialized equipment than an empty beer glass, a small pool of spilled beer and one beermat, between the months of August and September.
Instructions:
1. Spill small quantity of beer on to beer garden table
2. Await arrival of wasp on beer spill
3. Place upturned empty beer glass over wasp
4. Cover with beermat
5. Repeat steps 1-4 for subsequent wasp(s)
Trick is that a) captured wasps will always fly UPWARDS within upturned beer glass and b) the evil little fuckers, particularly with drink taken, will attack anything that comes to hand, including other glass-trapped wasps. Hence Celebrity Wasp Death Matches can be staged. There is no upper limit to the number of wasps that can be trapped under the same glass in this way. One long hot Summer we reached the heady heights of 30+ wasps under a single glass of a single lunchtime. TREMENDOUS SPORT! Boy they were MEAN!
But please, won't somebody think of the beer glass collectors. Warn them off aforesaid upturned glass. Tho if properly covered with beermat, surviving mean wasps are fully transportable, and a whole new world of evil opportunities arises. Not that THPP would ever condone such behaviour y'understand.
