Description:

In this final episode of the season, Dr. Valerie O’Brien joins the Yackers to take on conniving cuckoos, fake blood, and electrolysis in space. (So many bald astronauts!) Matt devotes his Chemical Minute to phosphorus and explains why “phossy jaw” may not be as much fun as it sounds. Finally, the team snorts some spice and stops by Arrakis to explore the confusing biology of hungry, hungry sandworms.
