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!

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"
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).

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.
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

if you read carefully you might be able to use it anyway
was no parachutes the teacher's rule? you wouldn't be able to make a big enough parachute with 7 pages anyways. but 1 piece of paper in a cone will protect an egg as long as your landing is perfect. i would make a cone out of 2 pieces of paper, crumple a third and put it in the nose, and then make some awesome fins out of the 4 other pieces

Yes no parachute was a rule, also would the fins really make the cone go down straight more? I tried it with out fins and it landed on it's side and splat.
I think an ice cream cone with *legs* of rolled paper, the legs soften the impact and provide balance when the tip of the cone hits the ground, it should work out well. Make sure the cone is very tight and the egg is fairly high up (the higher the better, but if its too high it might fall off)

yes the fins are really important for getting a good landing. if you've ever played with one of these in comparison with a normal nerf football you'll know what i'm talking about.

Those fins are sturdy, so i should roll up some more tubes then flatten them to make them look like fins?
I can think of a few ways that you can make a framework that will absorb the impact without affecting the egg as much, and also ensure that it will hit the ground and not transfer most of the force of the impact to the egg.
A cone is a good idea, except you actually want it to hit the ground on the circle face, not on the tip. This is because that when it hits the ground at the tip, it will absorb a bunch of the force, however, it will also tip over when it hits the ground and then smash the egg straight on the ground anyways (or at least transfer a lot of the impact to the egg)..... If you hit with the circle face, it will crumple without tipping, which is exactly what you want it to do.
I've been a physics teacher in a previous life. My head of department would always smirk about how the egg drop used to be a Year 7 experiment, then Yr 8, then Yr. 9 etc. during his 30+ years of service. At the time we were doing the experiment for Yr. 10's. I guess the dumbing down process continues...
Anyway the most successful ones I've been witness to have been very simple. Just get the paper and make a large amount of corrugations, just fold it into v-shapes so each piece of paper supports the other. Add tape. Tape the surface of the egg to stop cracks from propagating across the shell. Tape the egg to the topmost sheet. Put straws wherever you like (not really necessary).

ok I got curious so I actually tried this I used 2 pieces of paper. one I put in a cone and the other I taped flat over the top (so the whole thing looks like a T) it survived but the way it fell over sideways was kind of alarming, so I would recommend putting smaller cones pointing sideways to reduce the side impact.

make a cylinder and then put fins on the side that are slanted. Use any extra paper to make a crush zone at the bottom of the cylinder which will cushion the egg. The fins make the thing spin which decelerates and keeps it pointed downwards so that the egg will land on the cushion. Did that like 5 years ago when I had to do this experiment and could do 35m okay.
Edit: If you choose to go the paper route do this.
If you're trying to make sure the egg doesn't crack, and odds are the egg is going to impact something as it hits the ground, shouldn't you focus on ensuring that you stretch out the amount of time the impact is so that the overall impulse isn't that dramatic? (Not sure, but basically what I'm saying is do some cushioning) Unless the idea is to create a structure that doesn't break the egg, either way if you make it too rigid, the egg's inertia and momentum will just smash it into the inner lining of your now rigid structure. Once again, not sure. I'm very possibly completely mistaken.
I got a feelings the cone one might be the best way, my idea is that make a cone out of 1 sheet of paper, put some rolled up taper tube paddings on the inside of the cone and now what? = P

No kidding, I did this about 3 times with 3 groups of kids and presented the least effort/most effective, most successful way above. The corrugations should be about one inch wide.

this is also a good point
Which will be very difficult to accomplish with paper, because of air resistance..... With a straw framework, you won't really have to worry about that.
WAIT Since i can use 7 sheets of paper why not make like 5 cones 4 around the 1 cone with the actual egg in, and use the half a sheet to crupple up and stuff it under the egg to absorb some impact then use the other half to cover up the egg. Actually this is a pretty bad idea -________-

eh it's quite easy to just tape a piece of paper on top to get whatever orientation you want. But now that I think about it the point of the cone will absorb more impact than the base. I'm a bit skeptical about the straws since I've never seen it done myself while most winners used some version of the cone idea. But ~ava sounds like he knows what he's talking about, I'd try that too
honestly 2 meters is quite easy and just about anything reasonable will work.

I'm not sure if the 7th sheet is actually big enough to do that, bit this might work

It would be pretty crazy to drop out of physics because of a dumb egg drop experiment which has so little to do with physics lol

Here is thinking outside of the box: Why not just build that same plane again and put the egg on top of it?
We never got to do anything creative like that, our physics experiments were all straight up scientific-method things. Or analyzing water quality and stuff like that.
If you're going shock absorption, I think the best way would be lots of small triangles. You would have to find a way to cut it so you could get several stacks from each piece of paper and find a way to weave them together, but the advantage would be that you're not limited by the fixed area of each sheet so much as how finely you can cut it.
If you want to slow it down, maybe a circular tube so it would loop back into the tube continuously until friction decelerated it, then it would swing up and down like a pendulum until more friction caused it to stop. Not sure how you would support the tube.
The shape of the egg is such that it requires less force pushing from inside to break the shell than from outside. Good for little chicks trying to poke their way out. This is why if you use an egg to hit another egg, the one in your hand will probably break before the other one.
You should find a way to incorporate this into your design, but I don't really have much idea how.

Wait so the fins are slanted upwards right?
Yeah. Experiment with the angle/size of the fins to see what combination slows it down the most.
