Description
The Diet Coke Mentos geyser seems to have erupted onto the popular culture scene around 2006. Many analyses of the geysers focused on the "chemistry" of the eruptions: the interaction between the candy's shell and the soda.
To be a bit different, I created this activity to focus on the physics of the eruptions. When remote teaching/distance learning (RT;DL) came along, I was determined to keep this demo alive.
Initial and final masses are measured, as is eruption duration and apex height. From there, mass flow rate, nozzle speed, energy, and power can be determined. The fountain of fizz is a fountain of Phyz.
