Blog Post #13

Hey guys.  It's me again with another blog post.  Sorry but I'm going to be talking about egg drops again.  So this week we finally did our egg drops.  My partner and I made a type of box with tons of little foam cushions in it.  We made sure that the box was secure but has enough room for the impulse to push through.  There are a lot of physics involved in stopping an egg from breaking.  My partner and I realized that an average egg has a certain mass.  We used this to calculate the momentum of the drop.  We also realized that whatever we build has to not only cushion the egg from the bottom, but protect it from the impulse pushing down on the egg.  Therefore, we made a box full and placed the egg in the center.  This makes the egg experience the cushioning from below it and protect from the impulse pushing from above at all sides.  We also had to make sure that the egg doesn't shift around in the box.  So we made sure the the egg was secured in a protected foam wrapping and placed styrofoam packing-peanuts in the box.  This is because when the egg shifts around, it has inner liquids inside it, therefore if the liquids shift around a lot, the shell could crack from the inside.  We also had another problem that we never expected.  There was a ton of air pushing against the box.  This made the box shift slightly to the right.  However, this actually helped.  You see, when the air pushes on it, it increased the time of impact on the egg.  This will also help cushion the egg in a sense that the box will hit the ground slower.  But whatever the cause, the egg survived.  I believe the only modifications I would make on the contraption is maybe making adding a parachute, if possible.  If not, I would have just left it.  And that was our egg drop.  Sorry it was so long today.  But I hope you guys could try an egg drop.  And be creative on how to make it.
