Bungee Jump

Sent in by:
Rachel of Champaign, IL

Dare-deviled eggs! Design an eggy bungee jump and save the egg.

• eggs
• pennies
• nylons
• ruler
• scissors
• newspaper

## Instructions

1. Check with a grown-up before you get started. This can get pretty messy if your egg breaks.
2. Design a bungee jump ride for your egg.
3. The egg can not break or hit the ground and your bungee must come within 2 inches of the floor, without touching the floor.
4. Choose a launch site, such as a table or a ladder.
5. Use the nylons to make a bungee cord. Think about how stretchy the nylons are and how long the bungee cord needs to be.
6. Use tape to attach the bungee cord to the launch site.
7. Make a test egg; put some pennies in one hand and an egg in the other hand. Add or subtract pennies until the weight in each hand feels the same.
8. Test your bungee jump. Measure how close the test egg comes to the ground. Change one thing to improve your design.
9. When you are ready, try your bungee jump with a real egg. (You might want to spread newspaper underneath your launch site, just in case the egg breaks.)

Did it work or would you like homefries to go with those scrambled eggs? Now it's time to experiment. Think of a question you want answered. Like, what would happen if you used a larger or smaller egg? Would you need to change the nylons in some way? Be sure to predict what you think is going to happen. Then, test it out and send your reports in to our special feedback area. Every week, we'll publish a whole bunch.

We put a 4' ladder by a stack of chairs and suspended a pair of nylons between them. We then hung the other pair of nylons on the top pair and cut the foot of of one leg of the hanging ones. Inside of that foot, we put our testing pennies, the same weight as the egg. Then we tied the foot full of pennies to the bottom pair of howe, and dropped from the level of the top pair and measured the required drop height of 2". After we gave the nylons enough length, we put the egg in the penny foot and dropped it! It worked!!

It took some working, but I did it! I stretched out the nylon really good and long and I got the egg to drop 2 inches from the ground.

I did it and it never cracked because I put a cushion under it so the egg wouldnt crack.

My egg got sooo close to the ground it touched it but didnt break! I wonder how the egg would end up with a different nilon brand?

I did a variation of the Bungee Jump. I went out in my back yard and cut one leg off the nylons, put one egg in and tied the end to a tree limb about 5 feet off the ground. The egg didn't come close to touching the ground. So I tried adding another egg. Still the eggs didn't come close to the ground. I kept adding eggs until they finally touch the ground. I was able to get five eggs to bounce and touch the ground without breaking, but one egg broke when I tried six.

The first time we did it our egg came 2cm from the ground, and didn't break. Then the egg broke the secoind time because we made the nylon longer.

I did this for a Jr High school project and the first time I did it, the egg broke. The other time it did not broke at all. Then I tried a second egg it did break.

When I did the expirement I did it as a science expirment in school. As we tried it our egg broke 2 times and the third time the egg did not break and it was exactly 2in. from the ground. As the egg went back up it bounced out of the nylon!!!

We did some testing with a golf ball. We thought it worked. But when we tried it with the egg the first time it worked then we tried it again, and the egg broke.

When I did it the first time the egg was no where near hitting the ground. When we did it the second time the egg barely hit the ground and it broke.

We used a golf ball the first time and it worked. When we tried the bungee jump with an egg it broke. I think this happen becuase the egg was heavier.

Our egg (Genius) fell very, very, very close to the ground but did not meet its untimely death, until the fourth try. We kept tying it in knots so that it wouldnt stretch out to much. We tried a trial run with a golfball. What do you know it worked!
