Possible dumb question

[maelstrom]

This may make me look like an idiot but maybe not. I was just wondering if it would be safe for my newts to use part of a plastic milk jug to make a few more hides in their tank? Please let mr know either way. And seeing as i work at a dairy i can get unused jugs for free lol finally my job might have a perk : )
