Let's Bust A Myth: Is it possible to walk on eggshells?

And the myth goes on!

We've been asking people to submit myths to us in honor of our MythBusters exhibition. A few weeks ago, our STEM team tested the myth "Will your stomach really explode if you eat Pop Rocks and soda?" (Click here for the answer)

Now here comes our next myth, submitted by Karen M.: "Is it possible to walk on eggshells?"

We've all heard the saying "walking on eggshells" when we ask someone to tread lightly around a specific situation. With the help of eggs, bottle caps, and a plank, our STEM team attempted to figure out whether eggshells are really as fragile as we think:

As you can see in the video, this myth is confirmed – you really can walk on eggshells!

Eggshells are very strong. It all has to do with their shape: the catenary arch. This shape supports its own weight at every point, thus not needing any outside support.

Eggs have two catenary shapes, one at both the top and bottom of the egg. This natural design makes the egg strongest at these locations which is why they can withstand weight at these points.

An example of a catenary arch in engineering is the Gateway Arch in St. Louis, Missouri:
