Egg Drop Lab...SUCCESS :)

This week we did our Egg Drop Labs! I found this to be a very fun, interesting, and yet kind of challenging experiment to do because Kawai, Lydia, and I weren't 100% sure if our egg was going to survive! We used a 33 cm shoebox as our device.  We glued lots of cotton balls to the inner surrounding walls of the box.  After the box was all cushion-ized, we took a smaller box and glued cotton balls into it. This small box would be the object that held our egg in place.  When we received the egg, we wrapped it in black felt and taped it so that it was secure.  Once we were finished wrapping our egg in felt, we placed it into the small box and closed it.  We then put bubble wrap between the cotton balls on the inside of the bigger box and the bottom of the smaller box. We taped the small box to the shoebox.  We closed the lid of the shoebox and taped it so that it would not fly off during the drop.  If you watch the first video above, it shows how our egg was dropped.  In the second video, you can see that our egg survived the fall!  The reason why our egg survived was mainly due to the cotton balls.  We chose to use cotton balls because we knew that it would absorb the shock of the fall.  I really liked this lab because it was like a mini project and there was a little bit of suspense right before our egg was dropped.  I also liked seeing the various devices that the other groups created.  After all the eggs were dropped I came to realize that this lab wasn't as challenging as we made it to be.  One group had a very simple yet effective device.  They had three sponges.  They cut a whole in the middle of one of the sponges just enough for the egg to fit in.  After placing the egg in the whole, the surrounded the sides with the other two sponges (one on each side).  They then rubber-banded the three sponges together and dropped it! To me, this was the smartest device of them all because it was light in weight and it had LOTS of cushioning which would make the contact time of the sponge and the ground a lot longer than a shoebox would.  But, in the end, I'm just glad our device worked and our egg survived.:)
