Läskflaskan i berget — Varför sprutar lava som en fontän ur en vulkan?

Lava sprutar som en fontän för att magman har gas löst i sig under högt tryck, ungefär som kolsyran i en stängd läskflaska. När magman stiger mot ytan sjunker trycket, gasen blir bubblor, och bubblorna växer och knuffar ut lavan. Om bubblorna i stället hinner stiga upp och smita ut blir utbrottet lugnare, och lavan rinner ut. Den 17 oktober 2026 sprutade vulkanen Kīlauea på Hawaii lava omkring 220 meter upp i luften. I lektionen öppnar du en läskflaska, drar upp magma genom en vulkan, skär upp en lavasten full av bubbelhål och försöker lugna vulkanen. Första delen i serien Lavafontänen på Kīlauea.
