Drop Achievements [10 Achievements earned]

Drop Accuracy: We hit the BULL’s – Eye! We ran a string through a plastic straw taped to the side of the box and attached it to a rock to guide our box to the Bull’s – eye.

Egg Resilience: Our egg did NOT crack at all! The marshmallows and peanut butter were sufficient enough to protect the egg’s shell.

Calculation Achievements: Using a physics equation –

v=x/t

[[velocity = distance/time]]

For all of our products that had little wind resistance the time of the fall was fast. However, if there was some kind of mechanism inside like a rubber band or a marshmallow, the time of the impact slowed down considerably.

Therefore, the velocity slows down with an increase of time, resulting in less fore on the egg, protecting the shell from cracking

Other Achievements: A clever name for Egg Resilience would be: DPF – Drop Protection Factor

What designs did well?

Trent Shulte's design worked extremely well. His design was very creative, simple and effective. He made a card board box, surrounded an egg with tin foil and suspended the egg in the middle of the box.

No matter what way the box fell the rubber bands would slow down the egg to a safe speed. This was unlike other designs, because most of the other designs could only fall one way.

How would you redesign your project to obtain a better score?

I would change my design to use rubber band suspension instead of peanut butter to lesson the weight of my design. If money was no problem I would have put 20 helium balloons on the top of my box.
