What If You Fell Into a Volcano?

In the movies, Gollum sinks into the lava of Mount Doom. In real life, you wouldn't sink at all. We walk toward an erupting volcano one step at a time, with a timer running: from a slow lava flow, to the edge of a lava lake, to the invisible gas and the hot avalanches that can kill from kilometers away. Find out how hot lava really is, the fastest lava flow ever recorded, why you'd land on top of a lava lake, the lava bomb that hit a tour boat, the lake in Cameroon that breathed out a deadly cloud, and what really kills most people at volcanoes. In this video: • Why Gollum would not sink (and why the ring would melt) • How hot lava is, and how to read its temperature by color • How fast lava flows, and the record from Nyiragongo in 1977 • Can you walk on lava? The crust, the heat rays and the silver suits • What would really happen if you fell into a lava lake • Lava bombs: the 2018 tour boat at Kīlauea • Lake Nyos: the invisible cloud that reached 25 kilometers • Pyroclastic flows and Mount Unzen, 1991 • What has killed the most people at volcanoes • Kīlauea, still erupting in 2026 Chapters: 0:00 Gollum was wrong 0:55 How hot is lava? 1:33 Stop 1: a lava flow 2:15 Quiz: the fastest lava ever 3:10 Stop 2: the edge of the lava 3:39 Can you walk on lava? 4:18 Stop 3: falling in 4:28 Quiz: do you sink? 5:36 What really gets you 5:57 Lava bombs 6:43 Stop 4: the invisible killer 7:09 Lake Nyos, 1986 7:57 Quiz: how far can gas kill? 8:38 Stop 5: pyroclastic flows 9:21 Mount Unzen, 1991 9:55 Quiz: what kills the most? 10:37 Kīlauea, right now 11:08 The scoreboard 11:45 Could you survive?
