Hey Steemians,

today I have another little contribution for the sciencepic initiative:

It is a little funnel to fill liquid nitrogen in the Dewar vessel of an IR detector which only works when it is cooled. On the day I took the photo, we tested it for a longer time and filled the nitrogen in permanently. After a while, these tiny icicles began to grow on the outside of the funnel because of the (obviously) high humidity in our room.

I hope you like the picture. See you next time!
