ELI5: squirting water in hockey goal posts

r/

I don’t even know what flair this would fall under. At a hockey game, I noticed that in downtimes, someone would come onto the ice and remove the goal from the two holes that were holding it down. They then took a water bottle and squirted water into the hole, then put the goal back in place. I’ve rattled my brain as to why, but can’t think of anything!

    It freezes the post to the ice and prevents the goal from moving.
