Richard Hammond hosts TV's most leftfield engineering show.
Three brothers from Somerset and a team from Loughborough University are challenged to build ingenious chain reaction machines that will allow Richard to straighten his duvet and 'make the bed' without leaving the bath tub.
Less is certainly NOT more, as the teams use everyday objects to complete the task in the most complicated manner possible. Chain reaction machine guru Zach Umperovitch is the expert judge and Shini Somara fills in the science behind the teams' eccentric contraptions.
Richard Hammond's Crazy Contraptions begins Friday 29th April at 8pm on Channel 4 and All4.
