Episode #1.2

Liz cooks cockroaches and other insects for Dallas, Jem and Yan, as a food source that produces less methane during its lifetime than mammals such as cows and sheep. Jem produces and tests a jet backpack which uses the power of two fire-engine hoses to keep him aloft. Yan demonstrates how to inflate a balloon made from a long bin-bag by blowing *near* to its entrance rather than simply blowing into the mouth of the balloon. Dallas investigates whether any "Goldilocks planets" exist - those which have just the right conditions to support life.
