I believe the answer is:

crackers

I'm a little stuck... Click here to teach me more about this clue!

'things?' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for crackers that I've seen before include "Nutty - biscuits" , "nuts and > bananas" , "Crazy - (American) biscuits" , "Crazy types" , "they may be on the table at Christmas" .)

I've seen this clue in The Sun.
