# The Egg Drop/Mars Rover Simulation

## Representing Nasa's Rover Drop

The egg drop was meant to simulate the Mars Rover, and how we could prevent the egg (which was meant to represent the lander/rover) from breaking contact upon the ground (Mars).

I hypothesized if I used bubble wrap and foam, it was unlikely for the egg to break in the fall.

## The Model and How to Create it

For the model, it was created using tupper ware (what you have most likely had your lunch inside) twine (a form of string) a plastic bag, and bubble wrap. Hot glue and duct tape were used to hold stuff together.

How to

1) First, you need the tupperware. The tupperware is what you will hold the egg inside. Once you have hold of the tupperware, you will tear off five pieces of the foam, one for each side of the tupperware. If you have a circular tupperware, you need two, one for the bottom and one for the sides. Assuming you have a cubed tupperware, you will tear off five pieces.

2) Next, you will hot glue the pieces on the inside of the tupperware. It will act as a cushion when the egg shakes around due to impact.

3) Then you will get the twine, the paper bag, and the duct tape. You will thread the swine through the two sides of the bag, and rip off a piece of the duct tape (if needed, use scissors). The duct tape should then be attached to the end of the swine (not the paper bag, mind you). Then, attach the duct tape to the bottom of the tupperware. You know have a acting parachute.

4) Finally, you will get the egg and cocoon it in the bubble wrap, end of the bubble wrap to the top of it.

5) You will open the lid of the tupperware and place the egg inside. You are now ready for '' launch. ''

## Data (How the egg did)

The first round, the egg was dropped from 75 millimeters, and traveled at a speed of roughly 89.256 millimeters per second (it took .84 of a second for impact). For the second round, it traveled at a speed of 129.4 millimeters per second (.76 of a second), and finally, for the last round, 198.4 millimeters per second, with a drop speed of .63 of a second (the longer the height, the time decreased). During these three rounds, the egg did not break. Soon after, we had more rounds, but the distance was not recorded. It took .52 too drop, .76, and .9 seconds to drop on those rounds. The egg did not break during those either.

## Conclusion

The highest height the egg survived was one hundred and twenty-five feet+ (height unknown).

The highest known, exact height was one hundred and twenty-five feet, with a speed of 198.4 feet per second.

The design was effective, as it did not break or crack at all.

The science behind the egg drop is shown through Bernoulli's Principle; which states that an airplane (or anything trying to travel through space through anything other than water or land) must have a greater thrust and lift than drag and gravitational pull.

My hypothesis was accepted, as it did not crack due to the landing softened.

I could have added a bigger, more efficient parachute to slow down the fall.
