Perhaps this does not exist, thought I'd ask:
Asked DD6, if she could learn about anything what would it be. She answered, "portals." (from an elf movie she saw; I told her portals actually may exist.)

Does anyone know of a physics (how stuff works for 6 year old) book that explains relativity, string theory, portals, etc.?

Just looking for a fun book that illustrates basic physics principals, Newtonian, quantum, some of the weird stuff in comics that she would find interesting, introduces concepts, but isn't over a 6 year old's head.

Am I asking for a unicorn here?
