Humans controlling waterways by building dams has caused major problems for salmon, who must return to fresh water to breed. But a new company - Whooshh Innovations (not making that up) - has developed a better way to help salmon get upstream: a giant salmon cannon. Anthony thinks this is the perfect Rube Goldberg solution to the problem, while Jeff worries about a country that solves every problem by turning things into guns.
