I asked DS what he wanted for Christmas and he was typically, infuriatingly unhelpful, but he did say he wanted a water bottle of some kind. Apparently, lots of kids at his school have these and they're really cool. The trouble is, I can't remember what they are called. Obviously, I could ask him, but I am hoping he will have forgotten he said it and it will be a surprise.
Does anyone have any idea what kind of water bottle a 10yo kid would think is cool?!
