Superfluid Drip

High speed video of a superfluid drop pinching off from a nozzle. The temperature is 1.34 Kelvin (1.34 degrees above absolute zero). Video was taken in 2005 in the Taborek/Rutledge research lab a the University of California, Irvine.

Was I the only one hoping the last little drop would reach the big one before they went off screen?

I'm not sure what this was supposed to show relative to superfluidity. Can someone explain what this is supposed to show? It looks like a normal pinchoff, or was it to show that superfluids pinchoff the same as normal fluids?

the sun is dying, we need to send a team of cosmonauts to put the sun on a superfluid drip to recharge its zero-K reactor core

@DnlStnYtbr The technical definition of viscosity: a liquid's resistance to flow. For example, honey does have a higher viscosity than water because it has a higher capacity to resist flow. Therefore, it flows less quickly and changes direction less readily.

@DnlStnYtbr Viscosity is the thickness of the fluid. For example, honey has a higher viscosity than water.

@gaarafan93 Besides killing the tissue it touches, having a temperature of 2 Kelvin, the fluid will most likely just slip off your hand onto the floor, or maybe even climb on the surface of your hand. As it has been observed with liquid helium at 2 K, it can climb out of a container. But in my opinion it will slip off causing burns to your skin.

This is probably a redneck question but I need to ask. What would happen if this touched you? Since it is a very low Kelvin number I would imagine either it would literally burn right through you or it would completely freeze everything from the contact point through the rest of its position on your body, say the arm. But what would really happen?

@kizza314159 viscosity is the thickness or resistance of the fluid when it flows. If it has zero viscosity it's not gonna hesitate dripping

[kizza314159]

how can it drip if it has zero viscosity?

little drop at the end goes "hey, wait for me D:"

@zigfr33 do not confuse surface tension with superfluidity.
