Hello, I'm looking for any ideas that you geniuses may have! We have to design a device that will catch a (hardboiled) egg from 7 meters high. It can be made from any material/objects but must be under 5 cm tall (the sides can be as wide as wanted) and must be self-supporting. The device will...

I feel like have a chicken and egg type of problem regarding internal resistences because of the following problem: The voltage across a battery with internal resistence is given by the equation EMF-Ir=V Given the voltage across the battery then the voltage in the circuit is V=IR So, if I have...

I have determined in lab that a hard boiled egg is denser than a raw egg; however, I am not sure that I entirely understand this phenomenon. Assuming my data is correct, my assumptions are as follows: 1. Boiling the egg weakened its exterior, allowing water to enter the shell, thus increasing...

Hello... While digging in a nearby sand hill - brought sand used in building - I found 6 small eggs. I would ask you to help me identify for what species do they belong. Probable results: - belong to snakes- after comparing to some snakes' eggs size (Google images). N.B. it was in the Middle...

If an egg is thrown straight up in the air, then falls and reaches a point 30m below its starting point 5 seconds after it leaves the thrower's hand: What is the initial speed of the egg? How high does it rise above its starting point? What is the magnitude of its velocity at the highest...

Is the bottom half of an egg a hemisphere?

Hi, I am working on an Egg Drop Contraption as a Physical Science project. I need some help on a 1 page report I need to make. First, let me explain how my project will work so you can know how to answer my questions. I will have a box a bit bigger than the egg itself. The walls, floor, and...

My teacher is having us do an Egg Throw off of a building at our school. Further the distance, the more points we score on our grade. The project is pass/fail, if the egg breaks we get a 0. However, 60% of the actual project is a write-up explaining the concepts that happen to the egg as it is...

How it's going to happen: - 1 container with 3 eggs in it (they must be placed individually in ziplock bags) - Small to medium sized eggs - 3 back to back drops from 75m - Get all 3 eggs out within 20 seconds - The lighter the container WITH the eggs the better Restrictions: - No side...

Stop the presses! I've just come up with the perfect solution to the classic engineering challenge of dropping an egg from some hideous height and having it survive. Nothing that I've seen in any rules precludes it, and I can't believe that nobody has done it (or at least wasn't publicized as...

Hello, My physics class is doing the classic egg drop experiment, but with a different twist. We are asked to find the length of the bungee cord needed given a mass and a height to drop it from. The success of the lab is determined by how close we can get to the ground without touching. We...

I was experimenting with frying eggs in vegitable oil. The result tasted good but it made my mouth oily all day. I'm I going to be all right? How long is it till the oil is out of my body if ever. (I know oil is hydrophilic) Is my body going to be able to get rid of it?! Is the inside of my body...

Homework Statement I have to make an egg drop device. I was fishing for ideas. It needs to be the fastest time and survive the fall. If I win I get 4 points E.C.. Homework Equations Impulse = Ft Position function for falling object s(t) = -16t^2 +Vo + So s'(t) = -32t F = ma p =...

Hi, I have to make the classic egg drop contraption but we're only allowed to use plastic drinking straws, index cards, and hot glue. the width also has to be smaller than 4x4 inches but it can be as tall as we want it to be (but preferably small) and it has to have a door of some sort...

1. My assignment is to create an egg catcher to successfully catch an egg dropped from a height of a meter, the only materials I can use is: 1 Piece of paper 1 piece of aluminum foil 2 straws 20cm of tape What I was planning to do was create a cylinder with the paper and using the...

The basic idea is to package an egg so that it will not break when I drop it off a roof (assume 10m tall). The packaging should be as small and lightweight as possible. I know using a fluid will be rather heavy, but I'm still curious about his. How would I determine the optimal fluid to use? I...

Hi, can i know how to get the dielectric constant of the egg tray (the one with the paper) beside using dielectric probe technique? is it have same dielectric constant of paper? or it is different? i hope someone can help me. if the egg tray mix with the carbon or graphite, as i know the...

Homework Statement the egg of mass 59g breaks from a height of approximately 0.35m and breaks How much force does it take for the egg to break We know the egg broke at exactly 0.35m and any height less then that it was not as effectively broken? Homework Equations eg = mgh fg=mg...

The project requires me to build an Egg-Drop Vehicle that is ranked based on volume*mass (So ligher/smaller is better). And, of course, the egg can't break when dropped from 20 meters. critique my design please: http://img138.imageshack.us/img138/8872/eggdrop2.jpg Any suggestions or...

Hello, everyone, I am doing an egg drop for my science class, (not sure where to put it so I put it here, sorry if it's the wrong place.) and I have developed a few designs. I would like to know which you think would be most successful. (Dropped from gym class bleachers.) Parameters: Must...

Having a little trouble with this latest advanced egg drop assignment. The main assignment has two parts - 1. Create a rocket that can reach a minimum height of 120 ft 2. Create a vehicle that can land with an egg for a passenger, and not have it crack. We also aren't allowed to use...

I think it is the chicken. I can't understand why there is such confusion? Why is it compared to the promblem over the first genetic material formed? Is there any explanation on the basis evolution or mutation that supports the egg to be formed first?

Is a boiled egg a rigid body? Why does a rigid body, like a pawn, rotate? Thank you!

in physics we have to drop an egg 30ft and the only materials we have is 60cm of half inch thick clear tape, three sheets of paper, and four straws I am thinking about making helicopter blades for it and putting it in a modded paper water bomb with straws and paper bits as cushions but idk if...

I am given a milk carton (the small kind you drink in schools), and need to protect an egg by adding what ever I can inside the milk carton (nothing can be outside it). my teacher will first: 1) Drop it from the ceiling (9ft, 2.7 meters) 2) Drop a 16lb (7kg) bowling ball on it from a...

In my Honors Physics class we were assigned to construct a egg drop contraption solely out of tape, popsicle sticks, and paper. The first time I constructed it I made a paper parachute and attached a paper cone to the parachute (to hold the egg). Unfortunately, the egg broke upon impact. Any...

I just Balanced an Egg :( Right... so the ability to balance an egg on the equinox is a myth. Everyone knows this. So when, at approximately 8:15pm DST in Atlanta, GA, my husband pulled out the eggs to balance one, I was not impressed. Then he got one to balance. I was looking for the trick. He...

I am confused that many web sites say that it took 25 N to crack the egg, it's ok but When I do the drop test with 8 meter building. So, I calculate the force: 1kg(box) * 9.81m/s^2 So, the force tat impact my box is 9.81 Newton but the egg was crack. I just confuse!

Hi, we are doing an egg drop contest in my Physics class and I was hoping to get some ideas for the best capsule possible. Here are the rules: - No pre constructed containers (cans, boxes, bottles, glass, uncut plastic bags, egg containers etc) -capsule dimensions must not exceed 6 inches in...

Impulse Momentum Theorem + Egg Drop?? I have to explain how the impulse momentum theorem relates to my egg drop. My egg was padded with a styrofoam cup and tissues and a plastic bag parachute. Honestly, I don't understand the impulse momentum theorem and I am in need of help! I have fall times...

Well, I missed the opportunity to try this. Seems, within the first one two two minutes, you can balance a egg on its end when the Earth is at its solar minimum called the winter solstice..the shortest day of the year. Now, I figure, the Earth's gravitational constant in relation to the...

Homework Statement i need to make sample calculations of momentum using the mass of a standard egg (.05kg) dropped from 1 2 and 3 meter heights. but i have no clue how to do this

Homework Statement The egg protecting device cannot slow down the natural descent of the egg in any form: The mechanism used to protect the egg cannot rely on buoyancy (i.e. no inflated balloon-based solutions) or air resistance (i.e. no parachutes or solutions designed to increase the air...

why would a hard boiled egg spin and raw egg won't if made to spin on a flat surface?

My class has been assigned the egg drop project, and I need some help/info on how to go about it. Objective: to design a container which will protect a raw egg, when dropped. Apparatus: 1. Each container must meet the following specifications: a. Maximum mass- 20g...

My physics class is doing the popular egg drop experiment. We may only use wooden strips no larger than a 1/4" by 1/4" in cross section (ex: toothpicks, popsicle sticks). We may not use bamboo as it is a grass not a wood. We can only use glue, cement, superglue, or hot glue to hold it...

I have an egg drop project, in which we make a container on the ground that can cushion the fall of the egg. The limits are: 8 cm height max, and 45 x 45 cm box max area and the egg must not break even if it bounces out after hitting the container. It'll be dropped first from a height of 2...

I have to design an egg drop experiment for a teaching project. I'll describe the project and how everything works, then the students have about half an hour to create a container to shelter the egg so that it doesn't break from a fall of about 20 feet. The sticking point is the time limit. I...

So. This annoying project attack's again. I have to create a box to catch an unadulterated egg at the base of my school balconies. Starting at 18 ft. I have no clue were to even start! worse part, its due very soon and my 'group' refuses to help. I do not know what to do. my only limits are the...
