John is installing his weather station and Shannon is still pushing through finals week. On this week’s show we talk about a listener question regarding fulgurites. Can you petrify lightning and study it? Thanks to listener Steve for the show topic and fun paper suggestion!

• Lechatelierite
• Planar deformation features
• Lightning induced remanent magnetizations

• This week we scratch the fun paper itch - literally. Can scratching in a mirror trick your brain?
