While Liam Terry was testing out his new slow motion camera, he caught something pretty crazy... and hurtful.
His son kicked the ball and landed it straight into the face of his other son. One would think this was a delayed reaction, but it was really just the slow mo talking.
As much as it looked like it hurt, Terry didn't seem very worried. He even wrote on the video, "Slow motion kick to the head, so happy I caught this on camera!"
