Make sure the egg is lying horizontally in your hand so that one end of the egg is near your pinky and the other end is near your index finger. Once the egg is nestled nicely in the palm of your hand, try to make a fist by closing your fingers around the egg.
Your fingers should wrap around the egg and so that the egg is almost covered completely by your hand. You might want to hold your egg over the sink, bowl, or plate. We chose to do it over a countertop surface that was easy to wipe up the mess just in case the egg broke! When you realize the egg is not breaking, go ahead and use all the muscles you have to try and break the egg!
After a few minutes of squeezing with all your strength you will soon realize that breaking the egg this way is impossible! Using the hand that has a ring on it, squeeze the egg again as strong as you can and see if it will break this time! You might need to slide the ring up or down slightly on your finger until you get it into a position that contacts the egg while squeezing it.
The egg is more likely to break this time, so make sure you are holding the egg over a bowl, sink, plate, or surface that is easy to clean up. If you squeeze the egg hard enough with the ring on your finger, it will break and allow slimy, gooey raw egg to slide through your fingers! The unique shape of an egg gives it an incredible strength to withstand the force of your hand squeezing it.
The ends of an egg are the strongest points and act similar to the architectural design of an arch. Include your email address to get a message when this question is answered. If you're a little nervous about the outcome, try sealing the raw egg in a zipper-lock plastic bag before putting the squeeze on it, or hold the egg over the sink if you're in the super brave category.
Or go outside and try it. Helpful 0 Not Helpful 0. By completely surrounding the egg with your hand, the pressure you apply by squeezing is distributed evenly all over the egg. However, eggs do not stand up well to uneven forces which is why they crack easily on the side of a bowl.
Eggs are similar in shape to a 3-dimensional arch, one of the strongest architectural forms. The curved form of the shell distributes pressure evenly all over the shell rather than concentrating it at any one point.
Be careful not to wear a ring while squeezing. The uneven pressure of the ring against the shell will result in an amusing display of flying egg yolk. Helpful 51 Not Helpful Do not attempt this experiment near carpet, curtains, or any other hard-to-clean item. If this experiment fails, egg yolk will fly in all directions. Helpful 33 Not Helpful Don't try this in the store before you buy the egg. The storekeeper will not be amused. Helpful 0 Not Helpful 2.
One reason why this trick often fails to work, is that even an almost-invisible, hairline crack will cause the egg to break easily, no matter how evenly you apply pressure. The 3D arch structure is indeed very strong, but it only takes one minor flaw to weaken it dramatically.
Read up on the Paris Airport Terminal collapse for a larger-scale example of this phenomenon. So inspect the egg very carefully by holding it up to a bright light before you try it. If there's even a hint of a crack, use another egg. This only works if you perfectly apply even pressure.
Read the discussion page for examples of successful and failed attempts on this trick. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point. By completely surrounding the egg with your hand, the pressure you apply by squeezing is distributed evenly all over the egg. However, eggs do not stand up well to uneven forces which is why they crack easily when you push on just one side or wear a ring or why it cracks on the side of a bowl.
The uneven pressure of the ring against the shell will result in an amusing display of flying egg yolk for your audience members. This also explains how a hen can sit on an egg and not break it, but a tiny little chick can break through the eggshell — the weight of the hen is evenly distributed over the egg, while the pecking of the chick is an uneven force directed at just one spot on the egg.
After all of this, we were obviously reaching for more egg action! So, we then challenged each other to see if we could use our strength to crack the egg in any position.
