A short film made with cold neutron imaging at the Paul Scherrer Institut showing a moka pot brewing coffee, sped up four times. The neutron beam makes the water and steam inside the pot visible.
Recommended in moka pot threads as the best way to see how the pot works from the inside.

There's also a fantastic Youtube video in a neutron beam facility of a Moka pot, in which you can see the full process of brewing. The water and plastic handle appear 'black' as hydrogen scatters neutrons so strongly. ▶ this video
CT is the wrong imaging tech for Moka pots at least - they're much cooler looking if you're doing neutron imaging and can see the water: ▶ this video
For anybody wondering how a moka pot works, have a look at this neutron imaging of the pot in action: ▶ this video
