Egg Drop Lab


I thought our capsule would work because of a lot of things. First because our box was PACKED with bubble wrap and our egg was wrapped in bubble wrap and a small towel. Since our egg was surrounded by bubble wrap, there was no empty space for the egg to move around and crack. We put our egg directly in the middle of the box and this ensured that no matter where our capsule landed, no matter if it turned over or turned on it side, the egg would have the same amount of bubble wrap secured around it as any other side. Our capsule was also securely wrapped in duct tape that we knew would be very strong and keep the box from opening up. Our cardboard box provided a great, stable and not too small, not too big surface area. This surface area created a good amount of air resistance that pushed up on our capsule. Our capsule was also very light and because of that the gravitational force pulling down on it wasn't so strong. Another force that was exerted on the capsule was friction. All through the fall friction was pulling up on our capsule


Our capsule was SUCCESSFUL! It was successful because our capsule when falling turned a little bit around, it ended up landing on its corner which Mr. Blake said was the best place for it to land because that means the force of the ground is hitting the corner and not the whole 18.5 cm bottom of the box. Our capsule was very stable, we didn't take too many risks and we pretty much knew that our capsule would succeed because it was simple. The bubble wrap was a good idea. The bubble wrap definitely cushioned the blow, increased the contact time with the ground, and kept the egg stationary.
