The physics class made egg cases to learn about impact forces. We were testing how if the time of impact is increased, the force of impact is decreased. We dropped our egg cases, with an egg inside of it, off the bleachers onto the grass. Then we saw if our egg broke or not, and determined why or why not it did break or stayed intact.
   

For our egg case we used four circular Tupperware containers, honey, and duck tape. The outer three containers had honey filling the base of them to keep each box secured to each other. The innermost container was completely filled with honey, and had the egg submerged in it. Each separate Tupperware had the lid firmly on, and the entire egg case had duck tape ensuring that the containers would not come apart.
   

        Our egg did not break! The egg was safely dropped in an egg case that had a very light mass. Because of its lightweight, the impact force was decrease, and the time of impact was increased. These two factors allowed the egg to be fall and not break.

 

The design of the egg case would not have to be improved much, since it prevented our egg from breaking. In order to possibly improve it, we could use only two Tupperware boxes, more honey, and stronger tape to be sure the egg was secure. Using fewer containers would lessen the mass, causing the impact force to decrease more and the impact to increase more. Adding more honey would be necessary if using a smaller quantity of Tupperware because the honey would need to lessen the impact that the extra two containers would have done. By using stronger tape, we could be positive that our egg case would not be damaged.
You can use the concepts of the Egg Drop Eggstravaganza in many real life situations. For the long jump in track, sky divers, professional jumpers, ice skating, stunt men, cheerleading, hop scotch, dancing, squating, and jumping off of cliffs they all must bend their knees when they land in order to increase the time of impact and decrease the force of impact. Volleyball players must extend the time of impact with their arms in order to not hurt their arms, and to make the ball travel at a higher velocity.
