From the
Daily Mail:
The idea was to try to make the ‘spacecraft’ enigmatic and sinister rather than cartoonish UFOs.
The students constructed six oval flattened objects, 54 in long, 30 in wide and 20 in deep, moulded from fibreglass and laced with artist’s graphite to give them an other-worldly sheen. They looked more organic than mechanical, and indeed the team always referred to them as ‘eggs’ rather than flying saucers.
They decided that they would have to have something ‘alien’ inside them before they were sealed up. So they concocted disgusting jelly-like goo made from bread dough boiled at a high temperature. It looked like mashed human brain and stank to high heaven. Anyone who tried to break open one of the UFOs was going to be in for a nasty — albeit harmless — surprise.
Also inside each saucer was placed a small electronic loudspeaker, programmed to emit an unearthly wailing noise if the UFO was disturbed.
