In "Do Sumthin!" podcast, host Jodi Lee engages listeners with an educational and fun project of building a solar desalination still at home. An excellent activity for kids to learn about solar energy, the water cycle, and desalination, this DIY science experiment involves accessible household items such as a shallow container, plastic wrap, a small cup, saltwater, and a weight. The episode walks through step-by-step instructions on setting up the experiment and emphasizing the importance of patience and observation as the sun's heat initiates the desalination process. Jodi also uses this opportunity to discuss important environmental topics like the significance of clean water and the potential of solar energy in sustainable practices. The experiment also opens possibilities for further explorations and variations, thus fostering curiosity and interactive learning.
