Mad Labs is a British TV documentary series for the National Geographic Channel. The show focuses mainly on "wacky" experiments and inventions that may prove useful in the near future such as urine-powered batteries or solar panels with olive oil being the key ingredient instead of silica. While the show features real-life scientists and their inventions, a regular segment called "The Test Department" appears numerous times in an episode wherein the show's own testers perform experiments of their own.
