Can that save your bones?

In my project, I tested which materials are best to protect a person’s bones. The purpose of this project was to find out which material is the best to protect you from fractures and to use this information to make products that could protect the bones of anybody. I used chalks to replace bones because both of them have calcium in them. I used oobleck, sponge, EPE foam, and silicone as materials to protect the chalks from breaking. I predicted that oobleck would shield the chalks from the highest height and velocity. After I dropped the chalks and found out which protected the chalk from the highest height, I calculated the velocity of each chalk right before it hit the ground. I found out that oobleck protected the chalk from the highest height and velocity.
