You’re pinned in a back alley by half a dozen goons who have your wife and daughter in the back of their black SUV. You wait for a lull in the hail of bullets, then step out and put one round in each of them. Just as the last one’s going down his gun goes off and sparks from the bullet set the car on fire. You’re out of ammo and your family is trapped in the burning vehicle. You’ve got to think quick. Yes you could snatch up a fallen weapon and shoot out the window, but if you want to make sure those inside are kept safe you need to dig a little deeper into your bag of tricks.
For instance, do you have a ninja rock?
What is a Ninja Rock?
In common parlance a ninja rock is a small chip of aluminum oxide ceramic about the size of your pinky fingernail. You’ll get a few of them if you take a hammer to a spark plug. Once you’ve got a sharp little shard just throw it at the side window of a car and it shatters like sugar glass. They’ve been a trade secret of car thieves as well as smash-and-grab artists at least since 2001.
Why does that work? Because science, that’s why. You see the glass in the side windows of a car is strong, but it’s meant to shatter as soon as it’s pierced. So you don’t need to smash the entire window, because as soon as you pierce one part the rest tumbles right out. These particular chips of aluminum oxide ceramic focus impact in a way that other materials simply don’t, turning a little pebble into a weapon worthy of James Bond, Jason Bourne, or the Batman himself.

Do You Have An Antenna?
I know you do because as we said there’s a car right there. If you have a radio antenna you can break out the back window. Lay the heavy end of the antenna against the rear corner of the window just like in this video here, pull back the hammer, and let the spring in the antenna do the rest. It might take a try or two, but the antenna will deliver more than enough force to smash the window so you can get inside.
What if You’re Inside The Car, Smart Guy?
If you’re locked inside a car, then you’ve got a serious problem on your hands. So let’s make it worse by saying you’re in a locked car that’s been driven off a pier, and is sinking. To make it worse you’re in a rental with stuck windows so there’s not even a hope of an old wrench or prybar just floating around. Well as long as you can pull your headrest out of the seat, you should be able to pop that glass out in a jiffy.
No, no, not like that. The operative word here is pop, not smash for a reason. What you do is jam one of the metal spikes from the headrest down past the seal of the widow. You then pull it toward you. This force bows out the window and compromises the glass. Once that’s happened, as you can see in this video (you don’t need to speak Japanese to get the point) it’s easy to climb right out of your sinking vehicle.
Can’t I Just Punch It Out?
Remember the scene in The Terminator where the cyborg assassin from the future smashed through the windshield and it really freaked everyone out? That’s because while it might be possible to punch through a car window it’s very likely that people who do will break every bone in their hands. Even professional fighters can’t overcome the strength this glass is manufactured for without injury.
That said, if you’re going to constantly be breaking out auto glass it’s a good idea to keep a couple of firefighter tools on your person. There are handheld devices that use springs to smash out glass with a single movement, and even knife hilts with window breakers can be used to effectively hammer out a pane in an emergency. They might not be as much fun as a claw hammer or a crow bar, but these tools get the job done without earning you any funny looks while you’re off camera buying groceries or taking a walk in the park.
