There are a few things you can do to help get a car unstuck from sand. The first is to try to remove as much of the sand as possible. This will help make it easier for the car to move and will also help prevent it from getting stuck. The second thing you can do is use a plunger to push and pull the sand out of the way. This will help make it easier for the car to move and will also prevent it from getting stuck. Finally, you can use a vacuum cleaner to suck out any trapped air or gas. This will help make the car move more easily and will also prevent it from getting stuck.
