Summary

Description
Čeština: Analogický experiment ukazující vznik sopečné kaldery. Krabice naplněná moukou skrývá balónek spojený hadičkou, kterou se do něho začne nafukovat vzduch. Jakmile se přestane nafukovat, vzduch začne utíkat a začne vlivem gravitace pokles vyzdvižené mouky, což ilustruje proces, kdy dochází k naplnění a vyprázdnění magmatického krbu a následný propad. Experiment probíhal v rámci Týdne vědy 2010 na Geofyzikálním ústavu Akademie věd ČR, Česko.
English: An analogue experiment showing the formation of a volcanic caldera. The box filled with flour hides the balloon attached to a tube, which begins to inflate the air. Once it stops inflating, the air begins to escape due to gravity and starts to drop its elevated flour, which illustrates the process of filling and emptying of magma, and the subsequent drop in the caldera. The experiment took place during Science Week 2010 at the Institute of Geophysics the Academy of Sciences, Czech Republic.
