If neutrinos can move through vast quantities of mass without interacting with it, how are they detected?

Also, if there is some form of interaction, what exactly occurs?

Neutrinos are detected by using vast quantities of mass, like giant pools of water buried deep underground with detectors all around, so that the odds of a neutrino interacting with a single atom of that giant mass becomes high enough for the interaction to be detectable, say by detecting any photons that are emitted from the interaction.
