ELI5: How are goats able to eat things such as tin cans with seemingly no repercussions?

I don't think they digest the indelible things that they eat so they must defecate them out or throw them up, either way it seems like major damage could be done to their bodies & yet I continue to hear stories about goats eating anything you can imagine. How do they eat such strange things without damaging their bodies?

A lot of farm animals especially goats have powerful stomach acids. Pigs do as well and can digest almost anything but are smart enough not to eat anything that can go in their mouth. A goat is not too bright.
