Melissa and Jam delve into the intricate phenomenon of static electricity. They discuss their own experiences with static shocks and static cling, particularly in the winter months. They explain the concept of contact electrification and the tribal electric effect, providing basic explanations along with why these do not fully account for everything we observe. They highlight recent scientific research, revealing that much about static electricity remains a mystery, including why it occurs more in some materials than others and how friction affects it. The podcast also explores practical examples and ways static electricity impacts everyday life, such as in winter clothing, camp blankets, coffee grinding, and even industrial settings.

Melissa and Jam discuss the chemistry behind Poopourri Toilet Spray. Melissa explains how the spray works by forming a non-polar oil layer on top of water, preventing smelly polar molecules like skatole and sulfur compounds from escaping into the air. They also touch upon the practical applications and personal experiences of using the product, making everyday bathroom visits more pleasant. Throughout the episode, the hosts delve into the chemistry of solubility and intermolecular forces, providing an engaging and informative lesson on an often-overlooked subject.
