The trousers shown in the Wallace and Gromit film 'The Wrong Trousers' that allowed for its wearer to walk on walls and ceilings could theoretically work for 20 minutes at a time using a rechargeable battery.
This is according to a new research by students of University of Leicester. Katie Raymer, from Whitstable, explained that to walk on walls and ceilings it would be necessary for the trousers to be able function with only one of the boots in contact with the ceiling as well as both.
Raymer added that in order for the vacuum generator in the sole of the boots to work, they assumed that there was a slightly raised rubber insulator surrounding the boot of the trousers that would create a cavity which had a lower pressure than the surroundings when the vacuum was applied.
The study is published in the Journal of Physics Special Topics.
