Slug Experiment
The raw stats are:
Unprotected non-alcoholic beer: 4 slugs
Egg shell protected beer: 7 slugs
Copper wire protected beer: 11 slugs
Unprotected beer: 12 slugs
Conclusions
Marrying these results with those of my earlier experiments I conclude that egg shells give a small but enduring protection against slugs (so long as the shells are not dispersed by watering) while copper wire gives a strong but short lasting protection (possibly due to oxidization).
The presence of alcohol seems to increase attraction and also to change the nature of the corpses. The slugs in the alcohol-free beer were smoother and appeared to have drowned rather than been killed by an active agent leeching into the skin.
Further experiments
I would be interested to compare fresh wire with tarnished wire.
Artichoke Experiment
Over 50% of those present perceived a significant change in the taste of water after eating globe artichokes.
Methylated Spirits Experiment
Methylated Spirits cannot be filtered through bread.
Helium Experiment
Inhaling helium and reciting Mary Had A Little Lamb is indeed still funny.
Coke Fountain/Bomb
Spectacular effects can be achieved using a bottle of coke with a drilled lid, a paper clip and mint Mentos. I estimate the jet (from 2 1.5mm holes) at around 5m. However, the gas released from a bottle containing 4 Mentos was not sufficient to explode the bottle when an undrilled cap was used.
Grape/Microwave Experiment
A grape (cut equatorially and lightly dried) will smoke and burn violently when placed in the 'hot spot' of a domestic microwave. (The microwave still works by the way.)
Knotted Bin liner Experiment
A cheap alternative for the Queen's birthday fireworks can be achieved by suspending a bin liner (knotted at regular intervals) from a high place and lighting the bottom.
