James travels to an Oxfordshire town where a royal tradition desperately needs his help. Can he find a way of feeding thousands of locals to save their diamond jubilee celebration using ballistics and hot crossed buns?
Man Lab also tests once and for all whether it is possible to make your own luck by beating the odds. To put it to the test, James challenges Sim to the most dramatic drinking game you will ever see.
All this and there is still time for James and the team to build a water clock and create a coat that doubles up as a bed.
