Why does the lid come off when you use a blender with hot liquid but it doesn’t come off when you use it with cold liquid? Help me explain to my friend why it’s safer to let the steam come out and not over full the blender with hot soup.

When you blend hot liquid it aerates it creating more steam release which compounds with the thinner liquid rising further on the walls of the blender vessel. The fix is don’t seal the blender and don’t fill it more than half full you won’t have any issues.

Edit: as an FYI I have a Ninja Blender with two sets of blades that doesn’t have a totally sealing lid and I blend as much hot soup in it as I want without it doing anything dangerous.
