Please imagine there is a new designed tuna can with a particular cap opening design which requires a little thinking about the way you have to open it. Your friend gives you the can and asks you to open it. After a couple of minutes he returns to you and wants to ask you if you could open it. Which one of the following verbs works in my self-made sentence below? For me, they both mean the same:
Can you figure out how to open this?
Can you grasp how to open this?
Based on dictionary definitions, figure out works here, but in my opinion "grasp" should not sound weird to a native ear.
