The Challenges
The scientists begin by trying to find the best waterproofing agents for a tent, and look at the possibilities for insulating it.
They also build a seismograph and test it with dynamite explosions. The Rough Scientists have explained the science behind these challenges.
What makes a good waterproofing agent? Discover how material can be treated to repel water and what modern tents are made of.
