Double-Seater Canoe and Lie Detector

In 1945, Practical Mechanics included instructions of how to build a two-seater canoe that broke into two parts, so it could be transported by train.For their reinvention, father and son mechanical engineers Pete and Ellis come up with a very modern twist on making a lightweight, portable canoe.Taking inspiration from origami, the team create a foldable canoe made from thin plastic sheeting, fixed together by wooden bolts.It's brilliantly simple in design, but will it float Shini's boat when she takes it out on the water?Ellis and YouTube inventor Ruth are also tasked with modernising the Lie Detector that dates back to 1935.Instead of detecting lies, they come up with a device that uses A.I. face recognition software to detect emotions. They're also planning to set off some clever mechanical gadgets designed to change their subject's emotion.It'shighly ambitious, so will it actually work when Dr Shini puts it to the test?
