Empty water bottle? Lego's?

[Clueless]

Quick query. My Amazons love to play with things that make racket against the cage. If I remove the plastic ring and the paper that is on the water bottle - is there anything in a plastic water bottle that would be bad for them?

I also read somewhere about large Lego blocks. Can those be turned into parrot toys?

As long as they don't ingest them, probably fine. I know one owner was putting beads, treats and other items into water bottles, poking some holes in the side, then giving them to her birds!
