Recover data from broken laptop?

Hello I've had my laptop gone for a while. Because I was so stupid and my water glass was next to it, you can imagine what happened. How can

I now save the data or photos

Remove the hard drive and hang it on another computer.

Ok and how can I safely expand it

Unscrew the laptop. Just be careful. Some don't even have to open the whole laptop, but there's only one cover that has to be removed. You have to look there.

Depends on the model… Google is certainly helpful with a manual or video…

Thanks for your help
