Now this could be a personal safety tip, if you had to put a child or a pet in a car, but if you have to put you in a hot car left out in the sun, try this.
Open the drivers side door, roll down the window, and close the door.
Go to the passenger side door.
Open and Close the door widely 5 times.
According to physics what will happen is each time you open the passenger side door, you are actually sucking out massive amounts of hot air from inside the car, and it will dramatically lower the heat level inside. Try it!
