Experiement to investigate the explosive potential of electrolytic capacitors. Part 2
AJ PENTON, JD HALL, C REED et al. University of Cambridge. October 1999

Abstract

Electrolytic capacitors are known to be unstable when connected to dc power with reverse polarity. This investigation attempted to prove the viability of such devices as explosive devices. It was concluded that such capacitors are ineffective explosives, and, indeed are ineffective at anything other than being capacitors.


Investigation into the luminescent effects of high voltage on citrus fruits.
DA PIPET, CE HOWMAN, JD HALL, C REED, AJ PENTON, et al. University of Cambridge. May 1999.

Abstract

In an extension to the well-known phenomenum of electro-luminesence in pickled foodstuffs glow, an attempt was made to show that other foodstuffs containing a large quantity of acid also glow when mains current is passed through them. A variety of citrus fruits were tested for electro-luminescence in a similar way to that used to test pickles. The results were remarkably positive, not only do citrus fruits glow in a more impressive way, but they also smell much nicer while they are glowing.

AJ PENTON, JD HALL, C REED, DA PIPET, JS PIPET et al. University of Cambridge. May 1999

Abstract

Electrolytic capacitors are known to be unstable when connected to dc power with reverse polarity. This investigation will attempt to proove the viability of such devices as explosive devices. Thus far a preliminary investigation has enabled the scale of the effect and the precautions necessary to be gauged.


Experiment to investigate the materials used to manufacture pencil sharpeners
AJ PENTON, JD HALL, C REED, DA GEORGESON, JS PIPET, University of Cambridge. June 1998.

Abstract

An attempt was made to verify the hypothesis that pencil sharpeners are manufactured from magnesium metal. Test subjects were exposed to a high temperature flame, in an attempt to ignite them. Some of the subjects burned with a bright white flame that is characteristic of magnesium. It was concluded that old pencil sharpeners and the more expensive modern pencil sharpeners are made from an alloy that is principaly or wholly magnesium.


Investigation into the luminescent effects of high voltage on pickled foodstuffs.
BT WAINE, AJ PENTON, JD HALL, C REED, R YOUNGER, University of Cambridge, June 1997.

Abstract

A scientific investigation into the luminescent properties of a small variety of pickled vegetables when a large alternating voltage is applied across them. The differences between pickled gherkins and pickled onions as well as the effects of the separation of the electrodes are investigated.

The aim was to test the hypothesis put forward by John Hall that pickled onions and gherkins glow when a mains current is passed through them.


The Trojan Coffee Pot Affair
K GREENING, BT WAINE, JD HALL, SE BOXALL. University of Cambridge, May 1997.

Abstract

A private investigation into the migration habits of coffee pots.


A study of the feasibility of rapid ice cream manufacture.
CAPTAIN G TOLLEY, V NITROGEN KEEPER, HELMSMAN H, C GARRETT, University of Cambridge, Summer 1996.

Abstract

A short and low-key experiment in which ice cream is manufactured in two minutes by the use of liquid nitrogen as a coolant. The description is given in prose with some pretty pictures.


At this point it is necessary to point out that these experiements do contain real hazards, some of which are potentially lethal. While we do make a joke of taking unecessary safety precautions, we do also take REAL safety precautions. And, while in real science it is important to verify experimental results, the results described here are purely for your entertainment, please don't try to repeat them. If you must ignore our advice, or you think you know what you are doing, then it is your fault if you hurt yourself. Don't say we didn't tell you.
