A thought I had when I saw the original Steve Mould video, and this video made me remember it.
What happens if you just use glass for the bouncing surface? I was reading about the materials and I am not sure what property contributes to it's bounciness, but I think it is tensile strength(but it may be surface hardness). and regular glass has a slightly lower tensile strength than these amorphous metallic structures, fused quartz has a higher tensile strength, and I was unable to find out what tempered glass is, but I suspect tempered glass would tend to shatter if a small hard ball was bounced off it. Anyway, I was unable to form a good hypothesis as to what would happen, but I did find that mcmaster-carr sells fused quartz disks if anyone wants to try.
