If you have time and enough materials, give teams a chance to try another design, or repeat this activity on another day. When it is at rest or when you apply gentle pressure to the fluid, it acts as a liquid, but it quickly becomes a solid when under more pressure. To make the contraption, combine two parts corn starch with one part water to fill a quart-size plastic bag. Then simply stick the egg inside the bag and let it fall to the ground. When the bag hits the ground, the oobleck forms a solid around the egg so that the force of the fall is evenly distributed around the shell's surface.

Additionally, discussing the science behind each design choice can add to the learning experience. The goal of the egg drop challenge is to drop your egg from a height without it breaking when it hits the ground. Use toilet paper rolls as pillars to support and protect an egg, then use a sponge and rubber bands to hold it together.
Successful Egg Drop Project Design with Paper Only – Paper Funnel
STEAMsational was founded by Brenda MacArthur in 2011 and has provided STEM activities for kids and STEM curriculum to thousands of children around the world. Make your egg drop have a theme, like in our turkey Egg Drop Project with Popsicle Sticks. Gumdrop Bridge – Build a bridge from gumdrops and toothpicks and see how much weight it can hold. How Strong Is An Egg – Test much weight one egg can hold before it breaks.
Learning Objectives
Use cardboard tubes (toilet paper rolls or paper towel rolls) to create a protective structure around the egg. Surround the egg with a thick layer of cotton balls or cotton padding. This can absorb some of the impact forces upon landing.
When we dropped this package, it still fell pretty heavily (I’m not sure the balloon part was necessary), but the padding prevented the egg from breaking. I love the egg drop engineering project because it involves creativity mixed with a bit of physics. The goal of this project is to create a container that will safely deposit a raw egg onto the ground when it is dropped from something high. When I was a kid, we had a book about this egg drop engineering project, and ever since then, I have wanted to try it. We live on the third floor, so we have quite a long drop from our balcony, which is perfect for this experiment.

How Do Cotton Balls Prevent an Egg From Breaking?
This should work well for a standard two-story drop, but use larger bags and more cereal as the height of the drop increases. When the bag hits the ground, the impact of the landing is absorbed and distributed throughout the cereal. You’ll probably end up with a bag of crushed cereal, but the egg should be unbroken. Enclosing the egg in something that can absorb the force of impact can protect the egg from a fall.

Then, attach a plastic bag to the cup and launch it in a place where the wind can catch the bag. Most egg drop projects use many loose materials, design making, and tinkering that my son isn’t ready for yet. I thought we could expand on it by using materials in our kitchen to protect the eggs including ziptop bags to control the mess. The science behind this method lies in the property of sponges to absorb and distribute forces evenly. Sponges are made up of numerous tiny air pockets that can compress and expand to absorb shock.
More Favorite STEM Challenges
If you’d like to try with your kids or students, we have a free design process worksheet to help the design thinking. Many successful egg drop designs use sturdy containers to protect the contents from the initial shock of the drop. These hard containers may be plastic food containers or cardboard boxes. But the hard container alone is not enough to protect the egg completely. Styrofoam, sponges, cotton balls, bubble wrap or even wadded newspaper can all make good padding inside the container. Give your students time to practice with a variety of materials before dropping their eggs.

The big question with this egg drop is whether it will float down or crash. For a mult-step approach, make oobleck and cover the egg in oobleck. Then, put the egg in a cup that includes a soft packing material (mini-marshmallows, cotton balls). Cover the top with plastic wrap or tape and get ready to drop. The egg drop may be the most versatile activity there is.
Create your own egg drop designs to protect your egg from breaking when it is dropped from a height. The egg drop contest is an experiment usually performed by college or primary school students. Competitors typically attempt to create a device that can keep a raw chicken egg intact when dropped from a height.
Use grapes, cherry tomatoes or orange wedges between the egg and the side of the box or container. The fluid-filled cells work in a similar way to the air-filled bladders of bubble wrap. Consider that the egg must drop but is not required to hit the ground.
