EGG DROP
CHALLENGE

Can you engineer packaging that protects a raw egg from a 10-foot fall? You'll think, plan, build, and test — just like a real engineer.

Your Mission

WHAT YOU'LL DO IN THIS PROJECT

🔍

Investigate

Research what causes impact damage and how real packaging engineers cushion fragile cargo.

✏️

Plan

Design your own protective package. Sketch it out, label the parts, and explain your engineering choices.

🔨

Create

Build your package with the allowed materials. Document every step of the process.

📊

Evaluate

Drop it, inspect the egg, and reflect on what worked and what you'd improve next time.

The Four Criteria

CLICK TO JUMP TO ANY SECTION

🧠 Think Like an Engineer

There is no single correct answer to this challenge. Strong designs come from careful planning, creative thinking, and learning from mistakes.

Real engineers test, fail, adjust, and improve. That process is the work — not just the finished package.

EXPLORE MORE CHALLENGES

💥

Impact Force

Learn why a fast stop hurts more than a slow one, and how cushioning stretches out that stop.

🧴

Cushioning Materials

Compare how different materials absorb energy — air, foam, fiber, and structure all behave differently.

📦

Real Packaging

Look at how shipping companies protect fragile items — corner protection, void fill, and bracing.

Research Questions to Answer

What happens to an egg's shell the instant it hits the ground? Why do some packages fail even with lots of material inside them? What's the difference between cushioning and bracing?

✏️

Sketch It

Draw your design from at least two angles. Label every material and where it goes.

📝

Justify It

For each material choice, explain the engineering reason behind it — not just "it looked cool."

📋

Sequence It

Write clear, numbered build steps so anyone could follow your plan and build the same thing.

🔨

Follow Your Plan

Build the package you designed. If you change something mid-build, note why.

📸

Photograph Each Stage

Take a photo at every major step — this becomes your evidence for Criterion C.

⚖️

Stay Within the Rules

Check your material count against the limit before you call it finished.

🪂

Drop It

Drop your package from 10 feet onto a hard, flat surface. One drop, no do-overs.

🥚

Inspect the Egg

Open the package and check the egg. Record: cracked, dented, or fully intact.

💭

Reflect

What worked? What failed? If you rebuilt this tomorrow, what's the one thing you'd change?

Impact Force
The force an object experiences when it collides with something, like the ground.
Cushioning
A material that absorbs energy by compressing, slowing down impact instead of stopping it instantly.
Deceleration
The rate at which something slows down. A slower stop means less force on the egg.
Void Fill
Material used to fill empty space in a package so contents can't shift or collide with the walls.
Prototype
A first working version of a design, built to test whether an idea actually works.
Iterate
To improve a design through repeated cycles of testing and adjusting.
Structural Integrity
How well a structure holds its shape and function under stress or force.
Constraint
A limit on a design — like a material budget — that engineers must work within.

⚠️ Important

You may NOT use any other materials unless your teacher specifically approves them. Part of being an engineer is working creatively within constraints — that's the challenge!

📐 The Challenge Rules

Your package must meet all three requirements
🪂

Survive a 10ft Drop

Your package must be dropped from 10 feet onto a hard surface.

🥚

Zero Cracks

The egg inside must show no cracks, dents, or leaks after the drop.

📦

Max 15 Pieces

You may use no more than 15 total pieces of material in your build.

🏆 Remember

A package that survives the drop AND uses fewer materials scores higher — efficiency matters as much as protection. Aim high — your design could end up in the Hall of Fame!

🏆 Hall of Fame

Packages that protect the egg AND come in under the material limit earn a spot in the classroom Hall of Fame. Efficiency is part of great engineering.

🎮 How To Use The Egg Drop Lab

1. Pick a container — it sets your base protection and how it behaves in a fall.
2. Add up to 15 padding pieces — the same limit as the real challenge — each one adds cushioning.
3. Watch your Estimated Protection update live as you pack.
4. Drop it from increasing heights and see how far you can push it before it cracks.

1. Choose Your Container

Sets your starting protection and drop behavior

2. Pack Your Padding

Up to 15 pieces total — just like the real challenge

Estimated Protection
0.0
Real-World Target
10ft
Current Drop Height
0ft
3. Preview & Drop Test

Your package updates live as you build it above — drop it to test

💡 Why This Matters

More padding means more protection, but the real challenge also caps you at 15 pieces — so efficiency matters as much as raw cushioning. The Parachute Rig trades base protection for slower descent, which pays off more the higher you drop it. Testing more than once matters: this simulation, like a real drop test, has some natural variability.
