I wasn't a member. Only the assassins society which meant drawing a victim from a hat once a week and the victim had to avoid being stabbed by a joke shop knife in the neck by about 30 people. At which point you'd have to die a loud and horrible death wherever it occurred (usually in lectures). If the death wasn't loud and horrible as voted by the committee you'd have to pay the bar round. You'd get arrested now ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
Ah fond memories. Some friends at Uni used to play a game called 'killer' where there was a designated victim with all the other participants assassins who might work individually or in teams. The victim had the advantage of knowing who all the participants were, but still had to keep their guard up outside of designated neutral zones (such as the Union bar).
If you think you'd get arrested now for your version, tactics and weaponry consider the likely current response to the following.
Many of you will be familiar with the M72 LAW anti-tank rocket, shown here with the launch tube opened, the business end is to the left:
A friend, and participant in killer, John* had come into possession of a used LAW launch tube left over from an army exercise by perfectly legitimate means (His old school was the sort of place where the Combined Cadet Force got to go on
real military exercises and many CCF members legitimately expected to be running one of the services, or at least very senior in them, in 20-30 years time). Obviously this munition was spent and didn't contain the actual projectile, and moreover, the igniter mechanism had been fired so the thing was completely inert.
The igniter is that lump to the top right. It turns out that the heart of the igniter is essentially a .22 starting pistol that takes a .22 blank cartridge. It's cocked by extending the telescoping launch tube, decocked by closing it, and fired with a press trigger on the top, just to the left of the rear sight. There was also a manual safety pin (not shown) similar to the pin on a grenade, that had to be pulled out to unlock the end cap.
Although the igniter mechanism is single use, it's quite easy to dismantle and re-arm with a new blank cartridge. If you then seal off the base of the launch tube (right) all the exhaust gases from the blank go down the main body of the tube. Add some wadding with a couple of disks of thin cardboard to make a seal and you get a gas propelled piston that will travel the length of the barrel and then come to a halt.
If you top this piston with some shaving foam you have the mother of all custard pie throwers, accurate and effective out to about 20 feet. In one round of killer John deployed this as his weapon of choice, to devastating effect.
* Not his real name for obvious reasons.
