About this episode

The episode explores the science of welding and its applications through an interview with a welding instructor.

Did you know the welding arc can get even hotter than the surface of the Sun? 🔥 This week, we meet Rudy Rodriguez, a welding instructor at Weimar High School in Weimar, Texas. Together, we discover how welders use heat to join metal together, why they wear special helmets, what causes those bright sparks, and how welding helps build everything from playgrounds and roller coasters to bridges, airplanes, and even rockets! ➡️ Part of the Cool Jobs for Curious Kids series, made possible by Level Up Texas and the Texas A&M Office for Youth Engagement ⁠⁠https://tx.ag/cooljobs⁠⁠ 💬 Submit your kids' questions! ⁠⁠https://www.cumbrekids.org/questions⁠⁠ 🖍️ Coloring pages for each episode! ⁠⁠https://www.cumbrekids.org/color-along⁠⁠ 💛 Support this podcast by joining The Curious Club: ⁠⁠https://www.cumbrekids.org/curious-club⁠⁠ Orbit Family Conversation Starters!
