Egg Drop Challenge: Can You Save the Egg? - fun activities for kids and grown ups

 Can you build a contraption that keeps an egg from cracking when it falls from a height? There’s only one way to find out!

The Egg Drop Challenge is a fun STEM activity that combines science, creativity, and engineering. Kids get to design, build, test, and improve their own egg-protection system while learning about important scientific ideas such as gravity, force, motion, and impact.

The best part? There is no single “right” design. Kids can experiment with different materials and see what happens when their creations are put to the test.

It’s also a fantastic group activity. Invite a few friends or classmates and turn it into an exciting egg-drop competition!

What You'll Need

You don't need fancy laboratory equipment for this experiment. Gather some everyday materials and let the kids decide how they want to use them.

Materials

• 🥚 Eggs — have a few extras ready!
• Tape
• Scissors
• Bubble wrap
• Balloons
• Cardboard
• Drinking straws
• Sponge
• Cotton balls
• Rubber bands

Tip: You don't have to use every material. In fact, using fewer materials can make the challenge even more interesting!

How to Do the Egg Drop Challenge

Step 1: Plan Your Design

Before touching the materials, ask the kids to think about their design.

How will you protect the egg?

Will you surround it with soft materials? Build a box around it? Create a frame with straws? Use balloons as cushions?

Encourage kids to draw a quick sketch of their idea before they start building. This is the first step of the engineering process: plan before you build.

Step 2: Build Your Egg Protector

Place the egg in the center of your chosen materials and start building your protective structure.

Make sure the egg is protected from different directions. You can use tape and rubber bands to hold everything together.

Try to leave enough space between the egg and the outside of your structure. That extra space can help absorb some of the force when the egg hits the ground.

Step 3: Check Your Creation

Before the big test, give your egg protector a careful inspection.

Is the egg secure?

Can it move around too much?

Are there any parts that might fall off?

Trim any extra cardboard, tape, or other materials with scissors. Always have an adult help with scissors when needed.

Step 4: Choose a Safe Drop Zone

Now comes the exciting part!

Find a suitable place for your experiment. An outdoor area is usually best. Choose a clear space away from people, pets, windows, cars, and anything that could be damaged.

Have an adult help choose the drop height and supervise the experiment.

Hold your egg protector above the chosen spot and...

3... 2... 1... DROP!

Step 5: Check the Egg

Carefully pick up your creation and open it.

Did the egg survive?

If it cracked, don't worry! A failed test is actually a very useful part of the engineering process.

Ask:

• What worked well?
• Where did the egg crack?
• Which materials helped protect it?
• Was the egg too close to the outside?
• Could the structure be stronger or softer?
• What would you change next time?

Then make a new design and try again!

What's the Science Behind the Egg Drop?

So, what's actually happening when the egg falls?

Gravity Pulls the Egg Down

When you let go of the egg, gravity pulls it toward the ground. The longer it falls, the faster it moves.

The Egg Experiences an Impact

When the egg hits the ground, its motion changes very quickly. That sudden change creates a large force, which can crack the fragile shell.

Your job is to design a structure that helps reduce the effect of that impact.

Materials Can Absorb the Impact

Soft and flexible materials such as sponges, bubble wrap, and cotton balls can cushion the egg.

Other materials, such as cardboard, straws, and rubber bands, can be used to create a structure that keeps the egg away from the ground and spreads the force around the egg.

Some designs can also slow the egg down before it reaches the ground.

That's engineering in action!

Become an Egg-Drop Engineer

Want to make the challenge even more exciting?

Try changing one thing at a time and see whether it makes a difference.

For example:

• Drop the egg from different heights.
• Try using only three materials.
• Give everyone the same materials.
• Test two completely different designs.
• Add a parachute to slow the fall.
• Give each team a limited amount of tape.
• Keep track of which designs survive the most drops.

You can even create an egg-drop scorecard and record your results.
