Erupting volcanoes spew molten lava, gas and rocks up into the air. But just how high can the lava go and how do eruptions work? That’s what eight-year-old Thomas from Leeds in the UK wanted to know.
Thomas joined our host Eloise to put his question to volcanologist Martin Mangler from the University of Southampton on The Conversation’s Curious Kids podcast.
In each episode of The Conversation’s Curious Kids, a curious kid joins host Eloise to ask a top researcher their burning question. If you’d like to join in with the experiments in this episode, you’ll need some bicarbonate of soda, some vinegar, honey, a bottle or mug and a straw, to hand.
To listen to season two, follow us wherever you get your podcasts, or listen on the Yoto Player via the Discover section on the Yoto interactive audio platform for kids.
You can also listen back to season one and read lots of answers to questions sent in by children around the world in our Curious Kids series.

This season of The Conversation’s Curious Kids is supported by the University of Southampton in the UK, a world-leading research-intensive university with a global network of international students and campuses in Malaysia and Delhi.
