Recommended in moka pot threads as the best way to see how the pot works from the inside.

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.

“There's also a fantastic Youtube video in a neutron beam facility of a Moka pot” (HN, 2024)

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]
Full brewing process visible in neutron beam.
