Eggs stronger than bricks? | Live Experiments (Ep 3) | Head Squeeze

## TL;DR

This experiment tests the strength of eggs and whether they can support the weight of multiple bricks, showcasing the importance of their unique shape.

## Key Insights

• 🥚 Eggs have a unique shape, resembling a parabola, which contributes to their strength and ability to support weight.
• 🏗️ The parabolic shape is a basic shape of nature and can be observed in various phenomena, such as the trajectory of a bouncing ball.
• 🔪 In order to perform the experiment, the eggs need to be emptied and cut precisely to create identical shapes that can support the weight of bricks.
• ⚠️ Stress created during the cutting process can weaken the eggshell, making it important to secure it with masking tape to prevent crumbling.
• 💪 The experiment successfully supports the weight of one brick using the eggshell structure.
• 🧱 Adding a second brick proves to be too heavy for the four eggs to support, highlighting the limitations of their strength.
• 🔎 Experiments are essential for testing and determining the capabilities and limitations of different structures or materials.
• 😅 It is crucial to approach experiments with a sense of curiosity and an understanding that failures and unexpected outcomes are a part of the learning process.

## Questions & Answers

### Q: How does the shape of an egg contribute to its strength?

The curved top half of an egg, or parabola, gives it structural strength by effectively distributing weight and resisting impact forces. This shape is also commonly found in other natural structures and objects.

### Q: Why is it important to have four identical egg shapes for this experiment?

Having four identical egg shapes ensures that the load or weight of bricks is evenly distributed. If the eggs are not the same size, one egg may bear more weight, increasing the risk of collapse.

### Q: What is the purpose of the masking tape and marking the eggs?

The masking tape does not make the eggs stronger but rather helps keep them intact during the cutting process. Marking the eggs ensures that they are cut at the correct length, producing identical shapes for proper weight distribution.

### Q: Why did the eggs fail to support four bricks?

Supporting four bricks was too much for the fragile eggs. Despite the eggs being able to handle the weight of three bricks, adding one more brick proved to be too heavy, causing the eggs to break under the load.

## Summary & Key Takeaways

• The shape of an egg, specifically the top half or parabola, gives it structural strength, similar to other natural parabolic shapes in nature.

• Cutting an egg in half without causing it to crumble requires careful measures, such as emptying the egg, placing tape around it, and creating four identical shapes.

• While three bricks can be supported by the eggs, attempting to support four bricks proves to be too much for the fragile eggs.
