For physics we are doing a project and I need help with finding a way to either stop the bowling ball before it impacts the egg, redirect th bowling ball away from the egg, or make a contraption to push the egg out of the bowling balls way. We are only given these materials:
-150 toothpicks
-6 long skewer sticks
-5 sets of chopsticks
-10 glue sticks
-1 manila folder
Here are the requirments:
a. With the exception of saran wrap the egg doesn't have anything else touching it.
b. As far as the egg goes: no leakage
c: Only materials given can be used
d. Wherever the egg is located the bowling ball must be directly over it
Some important information is that the bowling ball is 14 lbs and will be lifted two meters directly above the egg.
So how do you keep it from leaking??

This is such a heavy ball falling 2 meters that I think the safest thing to do is to fling the egg out of the way before the bowling ball impacts. How can this be done reliably? Have the bowling ball hit a simple A frame at the apex so that the legs expand as the ball continues down. One of the legs can be affixed to a manilla folder, while the the other leg pushes a lever laying flat on the manilla folder, affixed to it at one end, but with the other end free to move as the A frame leg pushes it near the affixed end. The free end can be attached (by means of a "stick rope") to a cage containing the egg, thus whipping it out as the bowling ball drives down the apex of the A frame. I would suggest that the apex of the A frame be provided with a reasonably flat face for the ball to land on, and not push the A frame out of the way. So, plus all the little details that will need to be refined, this system basically involves an A frame and a lever arm resting on the manilla folder floor. With a little careful design, the egg probably can be flung out well away from the center after the ball has travelled only a couple of inches, pushing down on the apex of the A frame. In fact, you might even have to worry about the egg breaking from being flung TOO violently. Careful design, man.
You must understand that for this to work, you MUST have two points where the apparatus is affixed securely to the manilla folder which serves as the floor, and that those two points are approximately at opposite ends from the impact point. Moreover, you'll have to make sure that those affixed ends do have some degree of swivel before failure, otherwise the sticks will simply snap before the job is done.
The problem with "cone and bunker" protection schemes is that the bowling ball will have so much momentum, it'll simply push those things right out of the way before smashing the egg.
Oh, I should add, my apologies to Geologist Greg for ripping off his idea.

Make an A-frame around the egg, and attach a lever system, so that when the bowling ball impacts the top of the lever, it pushes the egg off to the side. The lever will need to be very strong to survive the initial impact.
Your other option would be to create a bunker from the toothpics. Use strips of the manilla folder to wrap around the toothpicks (placed vertically), and make it as thick as possible, with about a toothpick of height above the egg. Do not place anything above the egg. You may want to make it slanted, to direct some energy to the side.

Make certain the bowl your making use of has a skinny side and deliver the egg a pointy crack at the side - or use a desk knife at the same time protecting the egg to your palms. with a bit train you will have to be capable to do it effortless sufficient, additionally it is greater to crack your eggs right into a separate bowl so should you do drop shell you'll be able to fish it out with part of a further shell

breakdown every thing u have like rip up he folders break up he tooh picks gluesticks acept the chop sticks for a frame a cone shaped frame. use the egg (tall way up) as a base and a rurbber band to hold it together temp. mold the concoktion around the cone and let it dry out

Use the manila folder to make a tall cone that you place over the egg. Use some of the other materials to make it stronger.
