It occurred to me that I didn't fully understand why some metals are stronger than others. So in this video I wanted to find out, and then test it in a more fun way than anything strictly scientific. I cast knives out of two metals; Aluminum, and Lead, forged one out of steel, and printed one out of plastic. My goal was to learn why their strengths varied so much, and see if they can split a bullet.
