Two men are attempting to set the world land speed record for a motorised toilet.
Trevor Duckworth and Shaun Walker from Brighouse, West Yorkshire, aim to beat the existing record of 46mph (75km/h) held by a Canadian woman.
The attempt will be made at the Yorkshire Air Museum at Elvington near York on Saturday.
