Fun at the end of term - - 'Party time for volcanoes! How much force does it take to set off a party popper “volcano”?'
Measuring the force required to burst a party popper and relating the variable results obtained to the prediction of earthquakes, landslides and volcanic eruptions
This activity provides a quantifiable way of measuring a gradually increasing stress, akin to the build up of pressure beneath a volcano, or the increases in stress as rock masses begin to move relative to each other.
Many related activities can be found in the Natural Hazards category on the website.
