How do I get the lift open?

Have you noticed a panel next to the lift?

It's hermetically sealed. Maybe releasing the pressure will help.

Or even removing the pressure adjust valve altogether.

Now you have access to the inside. Via a very small hole, admittedly.

Do you have anything that fits?

Have you opened the vent? Come back when you have.

The funnel fits the hole perfectly. Huh.

Now what could a funnel be good for? Guiding liquid into a small opening, usually. Do you have any kind of liquid available?

The are some glasses for water on the table. Maybe you can ask someone to fill them?

Have you tried talking to Calvin? You never, know, he might be helpful for once.

Or not. But maybe there is a way to contact someone else?

Do you see a panel with a face on the wall? If not, keep talking to Calvin until his patience runs out.

Try talking to the panel. Then turn around – help will have materialized.

Why don't you ask the steward for some water? Or even better, chilled water?

Chilled, not frozen! Clumsy. Now the ice, having more volume than liquid water, applied too much pressure to the glass and broke it. Hmmm...

Use the funnel to ask the steward for more chilled water. If you like your chilled water inside wall panels, who's to say no?

Check the wall panel. Chilled to perfection. Now you only need to solve the puzzle behind it, and you're good to go.
