Ki Heim Chayeinu has teamed up with STAR-K to produce a series of videos exploring the practical halachos derived from the sugya of Hagalas Keilim, discussed in Pesachim, Daf Lamed. This episode features demonstrations by Rabbi Zvi Holland, Rabbi Chananya Jacobson and Rabbi Mayer Kurcfeld for the proper approach to kashering sinks and countertops; remarks by Rabbi Moshe Schuchman on the amount and size of bubbles required to meet the definition of "boiling" water; and concludes with a brief halachic discussion by Rav Moshe Heinemann on whether we may kasher plastic.
