Learning magic tricks from the Amazing Magic Kit while in the car during a road trip this summer can be a fun way for a kid to pass the time. They can practice card tricks, cup tricks, etc while in the back seat of the car. If they need a table they can simply use a piece of cardboard or even the box of some snacks you have packed for a surface to practice on.
By using boring down time to practice will keep your kid engaged and they may even get better practice in because there is nothing else competing for their attention!
Then once you get to your destination your kid can show magic trick to other campers, hotel staff, waiters, etc!
