The third season of Rough Science starts on the west coast of the southern island of New Zealand in an semi-abandoned saw mill. The challenges include panning for gold, making an accurate scale, and making a metal detector.
The challenges this week include making a water-powered sluice box, determining the year of the last big earthquake to hit the area, and making hand cream.
The Rough Science team visits the Franz Josef glacier to try to determine how fast it's advancing and how fast it's melting. They also need to make portable hand warmers.
This week the team must extract gold from the rock they found before, pan for more gold in black beach sand, and follow a treasure map. They need to make an altimeter and use the metal detector from before to find the treasure.
The team must make something from the gold they collected. They need to build a kiln and bellows to smelt the gold, then figure out what to make and how to make it.
