what is the rod like honey cartridges that is being pulled out of the rod in the environment video at 01:41

Hi,

Apologies in advance as I could not find which appropriate support/forum channel this question should be post against to.

This might sound like a trivial question but I was trying to find out what is the rod like honey cartridges that the engineer pulled out from a rod in your environmental video at 01:41 time mark.
