A Superfluid Faucet

Caption

This schematic drawing shows a nanoscale faucet: a long cylindrical channel connected to a container of superfluid helium. When vacuum pressure is applied to one end of the faucet's opening -- a nanopore -- helium atoms (represented here as pink balls) flow through, and are collected and measured as they spread out. An incredibly sensitive detector is needed to register the hundredths of nanograms of helium that flow through each second.
