Have any ideas for egg drop project?

Question

Goal: have a device that protects the (non-boiled) egg.
Must be less than 70 cm, and the mass must be less than 300 grams.
Can't use more than 1 linear foot of tape. Can't use plastic, batting, or cotton balls.
Has to be reusable.
Limited to using the following items: yarn/string, straws, glue, any amount of duct tape, toothpicks, rubber bands, cardboard, fabric, & either 1 non-helium iflated ballon, or 2 non-inflated balloons.

Answer 1

Duck tape the egg to the inflated ballon and weight down the other end.

Answer 2

you need to make a protective case that absorbs the impact so that the egg does not.

i would suggest using about 10 ft of string. now take that string and thread it through say 12 straws. maybe more than that......yeah alot more id say 20ft and more straws. now create a box for the egg to go in made out of cardboard and have the walls coated with duct tape. the duct tape on the walls should be kinda balled up so that when the egg is enclosed in the box it will be enclosed in a cushion like box. now put the egg in a balloon or wrap it once around with fabric. . now put the egg in the box. if you have to have it where the padded walls fold up around the egg.

now put the egg in the box and seal the box tightly with duct tape. it should be tight enough where the egg is not able to move around alot by no more than 1/4 inch but not so tight that the duct tape padding is commpressed againts the wall. now remember that long peice of string yarn that is covered with straws get that ready. there should be enough length of string at both ends to tie a knot without straws getting in the way......say 5 inches.
now secure one end of the string to your box and begin to wrap it around your box. the straws will overlap several times and it will create. a big ball of straws. this will absorb the impact. to get an idea of what the straws will do for your egg........get a handful straws and squeeze the straws if things go as plans will cushioun...better yet lay them on a table and and press down on alot of them.

they are soft abosrob impact and are not so soft that the impact will go straight to the egg. what you felt when pressing on the straws is what will be wrapped aournd your egg....those strawss absorb impact while the box will help even more by absrobing any impact the egg may recieve and keeping the egg from jolting.

but the straws are your best bet for impact absortion. they would work better than anything. if you have to cut a bunch of straws into lengths of 1 inch and then put the string through them so that way when they are wrapped around the egg they will not buckle or crease from being so long.

it would be alot easier if you could cut some foam from a temperpedic bed or whatever it is called

but yeah dont wrap the straws around it to tight because if you do they will not have as much room to compress against each other on impact because they will will already be compressed. and that is how they will absorb impact. but dont have them to loose either.

Answer 3

Make a little tape bowl just bigger than the egg and 2/3 as tall. Glue a string to the end of the egg and suspend it 1/4" above the bottom of the bowl. Fill the bowl with glue, encasing the egg. When it dries, finish making the tape egg enclosure except for a small hole on top. Fill it the rest of the way with the glue. Wrap the whole thing up with the rest of your tape.

Answer 4

If the undertaking is to drop an egg and have it land with out breaking then do this. Make a parachute out of a bag and connect a basket to it utilising 4 bits of string (one at each and every nook of the bag). Wrap your egg up in newspaper or bubble wrap, positioned into the basket and drop. optimistically the parachute will open and the egg will arrive properly on the floor. Your basket would be made from something - a twig can lid, a plastic bottle with the suited decrease off etc. have relaxing.

Answer 5

first take a balloon and air it up, then take a piece of fabric and tie it over the biggest part of the balloon. Then take a small cardboard box and strap it to the botton of the balloon. Take some strong,but soft fabric and layer it around the inside of the box. Take a smaller box (big enough to put your egg in) and layer that box with fabric also. Put the smallest box into the bigger one and attach the box to the parachute. Make sure that your parachute's size is adequate enough to slow down the fall of the box. If done right this works

Answer 6

Your list of items is disappointing. I didn't smash my egg off the roof of the high school since i put the egg into a large, slightly chilled jar of vaseline. But, the concept is the same. You want the impact energy to be transmitted around and not into the egg shell. So, keep that in mind in your design efforts and good luck.

Oh, and I did not say I won the contest, just that my egg did not break in any way. I was not permitted to win since I technically had not "built" anything. But, I did achieve the goal of the competition. Also, my physics teacher said he could not give me ANY points for being such a smart a**, no matter how "original" I thought my idea/design.

Answer 7

Duct tape the cardboard into a box, fill the box with fabric, and put the egg in there with it.
I won one of these contests when I was little.

Answer 8

2 basic ways you could go

Either cushion the inside of a cardboard box so the egg is protected

Or suspend the egg inside a box so that it doesn't touch any of the sides
