The summary is:
The video is about testing the bullet-stopping power of real kinetic sand, a type of sand that acts like a fluid when moved. The narrator shoots different calibers of bullets at bags and piles of kinetic sand and compares the results with a previous video using fake kinetic sand. He finds that the real kinetic sand is better at stopping bullets and self-healing the holes. He also recovers all the bullets he shot and offers some of them as prizes for his merchandise buyers. He jokes that the military should use play sand for their sandbags and that he wants credit for his idea. He ends the video with a rule of demolition and a scream.
