There aren’t many things worse that locking yourself out of your car – you have surely put yourself in this kind of situation at least once in your life and recall it with horror. But, did you know that there’s a simple trick with a tennis ball which will open your car in a second?
Here’s what you should do: take a tennis ball and pierce it in the middle with a screwdriver or something sharp. Now, press the opening against the keyhole of your car and press the ball as hard as you can. The air pressure inside the ball will increase and force the door open, unlocking your car immediately! Nifty, isn’t it?
This amazing trick even works for electric locks. From now on, be sure to carry a small tennis ball wherever you go – you never know when you can lock yourself out again!
