Need egg drop project ideas

  1. 1. The problem statement, all variables and given/known data
    Im sure most of us have heard about and done an egg drop project sometime in our lives, and right now is the time to do mine.

    We will be dropping the egg that is inside of our project from the second story of a building, and then from the third story. We are allowed to use any kind of glue, toothpicks, and drinking straws. The glue cannot be attached to the egg after its landed (meaning no wet glue or gluing the egg to something), and the egg cannot be modified (cannot be soaked in vinegar, etc). The project has to weigh less than 200g, and bonus points are awarded for projects less than 100g.

    3. The attempt at a solution
    This is really the only idea I have come up with.
    Make a small box to put the egg in out of toothpicks, then put a layer of glue down to hold the box together. Put another layer of toothpicks and glue down for more reenforcement (I have to drop this twice). Then evenly space the straws apart and cut them so they fit horizontally into the "box", and keep switching the direction the are facing as each row is layed down (my thinking here is the straws would provide cushioning for the egg with air gaps all around).

    So is this even worth a try? Anyone have any other ideas?

    Interesting twist on an old assignment. In general, the egg that survives will be the one in the box that is allowed to shatter or crumple.

    I'd ditch the toothpicks completely and try a geometrical ball of straws, as larges as possible and with as much space as possible. Use a good plastic cement, and hold the bonds with clothespins till they are set.
  4. Thats actually a pretty good idea. Are you saying just get a bunch of straws, twist them around and wrap each straw inside of itself, and then glue it all together? Need egg drop project ideas

    Straws are strong (at least axially) and are very lightweight, and they have a cross-sectional area that makes them better for air-braking than toothpicks. Ditch the picks. You may want to consider constructing a container from straws that is shaped in such a way to incorporate air-foils that will cause the container to rotate and air-brake its way to the ground. Any ideas now? I'm not going to go any further in this advice until you come up with some viable lines of attack.
  6. u could use the ball idea and make outside out of straw as well. but stick the toothpicks through the straws as added support and it should work well. if a toothpick or 2snaps it shouldbe fine. the straws should cushion most of the fall and if u can make it rigid enough the egg might not slam into the straws. good luck
  7. This is not a sophisticated idea, but for my egg drop I simply filled a box with cheerios and placed the egg inside. The cheerios break easily and spread the weight of the egg nicely. Not only that, but they're very light and no complex construction is required. My egg drop survived a drop of about 20-30 feet with no problems at all, though I never tested it higher.

    Don't overthink the matter!
  8. Cut a block of styrofoam into a stout cylinder and hollow out the inside so the walls are about an inch thick. Cut cardboard, or thick paper into a circle, about the same diameter as the styrofoam, and put it inside in a cork screw shape. Make another styrofoam cylinder, a tad larger than the egg, and, after hollowing it out, attatch it to the bottom of the "screw". Placing it on the bottom will give it some pull, which will make it spin and decrease the downward acceleration.

    Better start breeding a 200g chicken then.

    I only come up with brilliant innovative 'thinking outside the box' solutions - it's upto engineering to make them work!

    I'm afraid in this case you need some outside the chicken thinking.

    Memo to marketing ...
  13. When I did this in grade 1, I used a 2L pop bottle (one of these: sprite 2L.jpg - image found through google), cut off the bottom, filled it with foam sponges, stuck the egg in the middle and added more foam sponges. We couldn't get the egg to break just by dropping it.
  14. I remember some headmaster hiring a helicopter so he could throw eggs out the door and prove to his no doubt underwhelmed pupils that at least some of the eggs would survive as long as they reached terminal velocity. Birds have had some evolutionary time to perfect this sort of thing.

    So throw the eggs as high as you can and maybe that'll work.
  15. use cotton balls to buffer the eggs from impact

  16. Are you limited to only straws and toothpicks? If not, I suggest ditching the straws. I just got the paper for my egg drop (actually more like "egg chunk") project today, and the teacher showed us videos of last year's projects. The egg in the straws died.
  17. This a good idea, egg drop

  19. good idea!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! no 1 has EVER thought of that i mean come on these people still have common sense
  20. Well, we have the same thing that is due in 2 days, on Thursday. The rules are: The supplies used to make your project must be biodegradable, and it must be in a biodegradable box. Thats all. And what I did was take a tissue box, I bought some cotton balls at the store, I took the tissues out of the box. Then I crumpled the tissues up, put the cotton balls in, and stuffed the egg in, surrounded the egg. You can use that idea but please try to add a different detail in it. Just I thought it up myself lol. But feel free to use that idea. Also, if you want, you could probably add a parachute to it, you know, to make it drop easier and more slower. Ok, gtg. Bye!
