So, in my physics 11 class we're suppose to construct a egg protector out of 7 sheets of paper (A4) and 1 meter of tape or 10 straws and 1 meter of tape to protect one egg that is suppose to be dropped from around 2 meters (around 6.6 feet) I've tried everything possible but my egg keeps breaking.I made one with a cone around so that when the tip hit's it'll crumple and reduce the impact, BUT it's kind of risky if i accidentally drop it sideways...
Most of my friends told me to just wrap the egg around with 7 sheets of paper and don't give a shit about these ridiculous labs/experiments but i want to keep my #1 status for lab/experiments wins
(Recently won a paper airplane competition to see whose plane can stay in the air the longest)
Materials: 7 sheets of paper, 1 meter of tape OR 10 straws, 1 meter of tape
Also, no parachutes = (
Anyone have any other ideas?
Thanks so much!

Holy shit, I thought physics 2 sucked, THERE IS 9 MORE OF THEM!?!?!?!?

Physics 11 as in grade 11 physics = P (Teachers a real bitch too, can't teach for shit)
|
have u tried google?.. egg dropping is like the most common physics experiment known to man

I did this plus a parachute when I did a similar project in high school. It was successful.
This is one of those projects that sounds great in theory but really is a waste of time!!! Oh god look how much physics you learned!
edit: what do you mean teacher can't teach for shit? can you elaborate?

Oh a friend's sister told me about this experiment in her class about 5 years ago and how she managed to do it, but I don't remember what she did, I'll ask her and if she knows, i'll tell you.

Lol she just tells us to do the experiments with what we know, which is practically nothing because she didn't teach us about this. The only part she taught was impulse and momentum, and that "its better if the impact takes more time because it loses force"
PS.No parachutes = (

There's a few ways of doing it.
Parachute.
Making a box type thing for the egg into a bigger box which shields it You can try like semi suspending it in the middle which shitloads of tape.
Impact takes less time just means you want it to budge slowly which means that if the system lands with the egg falling first theres no room for the paper to slowly bend, but if the egg is at another side or there is some cushion space the paper will bend slightly and the impact will be much less. More paper on a wide area means that a larger air resistance will reduce velocity more reduces the impulse that way. Mass of the paper is neglible and mass of the egg is constant, so you have to work with velocity and time of impact only.
To make a cushion layer you want a large amount of paper at the bottom and then you can make some kind of hammock for your egg box if suspending it with tape in a small paper box doesn't work. 7 sheets sounds small though.
1 sheet cut up to form the small box.
4 to form a bigger box may need to cut it up.
Use 2 on either side of the box one to hold it up one to absorb energy if it flies up then goes back down again.
1 metre of tape sounds like a lot but mostly you need the strength on the hammock bit the boxes are only being pushed apart by air currents formed by the fall.

Stupid physics labs, I can't build battlecruisers without them.
Make a box in a box, and use the paper to attach the inside corners to the outside corners. You can make straws out of paper lol, roll them up and use tape (incidentally the first straws ever produces were made of paper)
edit: as in, make a box around the egg, make eight paper straws to attach the corners of that box to the corners of the outside box. Any leftover paper should be shredded and used for padding.

The crumple cone is the most effective method of protecting an egg, proven by middle school science projects all over the world. Just make sure you put something to stabilize it and keep it pointed downward (a long tail or a parachute).

yeah, google is your friend here. Just typing "egg drop" into google image search brings up like ten different designs.

A smaller box within a bigger box being suspended i the air with paper straws? Did i mention i'd probably have to do this test multiple times = P

Form a mini hammock inside the crumple cone imo. Just 1/2 a sheet with some tape should do.
YO DAWG I HERD U LIKE BOXES SO I PUT A BOX IN UR BOX SO YOU CAN PROTECT YOUR EGG WHILE YOU'RE PROTECTING YOUR EGG!
Come on, tell me that one didn't crack you up.

I did google this up but my teachers material requirements are crazy, i can't find shit that only uses 7 sheets of paper and OR 10 straws -_____-

LOL I think i might make a box in a box to protect the egg just to write this outside the box.

I once saw this work when some one built a big plane. The thing looked like space ship with a flat bottom. The thing flew about 30 feet and landed very gracefully. If you combine this with your airplane design...
you can also go with the crude helicopter design. Make it look like a carrot with a T on top, and the design will spin, reducing impact speed. Also, it will ensure that the egg will fall the correct way for your cone to work.

1. roll up sheets of paper into tubes
2. tape to egg creating a paper jack shape (make sure there are no big gaps)
3. Tape straws between the tubes to strengthen (make triangles)
4. drop
5. A+
you can just leave out teh straws and use strips of extra paper too

Kinda like that 
Guys he's not allowed to use a parachute.
edit: Paper OR straws, not both.

Would do this IF i was allowed to use staws AND paper. But i'm not = (

if you read carefully you might be able to use it anyway
