Those cardboard rolls can be used for lots of things when your a little kid. I remember making stuff with them, I just can't remember what exactly! lol
(Yes, I do too. We made little robots out of them, and decorations and whatnot...you know, draw stuff on them, and put wrapping paper around them to make them look like Christmas crackers. Nowadays you're not allowed to do that any more over here - we got a letter last year from school that the kids are not allowed to use the rolls from toilet paper or paper towel because of 'hygenic reasons' anymore. )
