Egg Drop

Purpose

The Egg Drop challenges teams to design and build a container that protects a raw egg from breaking when dropped from height. It combines creative thinking, engineering principles, iterative design, and resource management. The exercise rewards both innovative design and willingness to test early, making it an excellent metaphor for product development and prototyping.

At a glance

• Group size: 8–40 participants (teams of 3–5)
• Duration: 45 minutes
• Difficulty: Beginner to Intermediate
• Facilitation style: Timed challenge with progressive reveals
• Setting: Indoors for building; outdoors or stairwell for the drop

How to run

1. Brief (5 min): Your team must build a container that protects a raw egg when dropped from 3 metres (or higher). You have these materials and 25 minutes. The egg must be recoverable and intact after the drop.
2. Build phase (25 min): Distribute identical kits. Teams design and build. Give time warnings at 15, 10, and 5 minutes.
3. Drop phase (10 min): Each team drops their container. Build drama — count down, let spectators watch. Check each egg.
4. Debrief (5 min): What design principles worked? Did anyone test early? How did you allocate roles? What would you change with more time?

Materials needed

• Raw eggs (2–3 per team for testing and final drop)
• Building materials per team: straws, tape, newspaper, bubble wrap, rubber bands, plastic bags, cardboard
• Drop location with measurable height (balcony, stairwell, ladder)
• Tarp or bin bags for cleanup

Pitfalls & common mistakes

• Drop height too low: Below 2 metres, almost anything works. Aim for 3+ metres.
• Too much material: Abundance removes the need for clever design. Constrain the kit.
• No cleanup plan: Broken eggs are messy. Have paper towels and bags ready.
• Judging only on survival: Also celebrate innovative design, lightest container, most elegant solution.

Inclusion & accessibility

• Provide a variety of tools (left-handed scissors, easy-grip tape dispensers) for different physical abilities.
• Assign meaningful roles for participants who cannot do fine motor tasks (project manager, designer, tester).
• Consider egg alternatives for vegan participants (water balloon with paint).

Variations

• Egg Drop with Budget: Each material has a price. Cheapest surviving design wins.
• Extreme Egg Drop: Increase height progressively. Last egg standing wins.
• Naked Egg Drop: No container — teams can only modify the landing zone.

When NOT to use this

• In settings where food waste is culturally sensitive or logistically problematic.
• Without a safe, supervised drop location.
• With groups that react very negatively to failure — broken eggs are inevitable.
