We'll be doing a drive to florida from michigan with an almost 3 year old and 4 1/2 year old boys. I'm looking for stuff to keep them busy when they aren't sleeping in the cars. I've got tonka magnetic books, lacing cards, magnadoodles. Maybe some small magnetic puzzle mazes. I'm looking for something like a rubiks cube that can be manipulated, twisted, make shapes etc but at their age level and that doesn't come apart. Looking for something that doesn't have lots of little pieces to get lost in the car and definitely stuff that doesn't make noise.
Also looking for suggestions for non-toy stuff to make the trip easier.
TIA!
