It's been described as getting hit with a basketball thrown point blank at your face, but if you ever experience an airbag deployment, you're probably not going to complain, since it most likely saved your life. Unless you're a glass of water, as this wonderful high-speed footage reveals.
In yet another mesmerising clip, The Slow Mo Guys reveal just how fast an airbag inflates. So fast, in fact, that it's barely captured in a few frames in this high-speed footage. But it does confirm that if your companion is a glass full of water, you'll definitely want it buckled into the back seat of your vehicle.
