A Pringles can is the perfect size and shape to protect an egg. First, decorate an egg like Humpty Dumpty (smiley face, overalls). Then, fill baggies with different materials like water beads, sand, pasta, and cotton balls.

Egg Drop challenge is a project-based STEM challenge that can be adapted to all ages, from elementary to high school. The basic idea is to design and build a container to hold a raw egg that can protect the egg from breaking when dropped from certain height. Through the project, students learn engineering design process, physics, material science, and if it is a team project, team work. A simple padded box may likely be the most common successful egg drop contraption. The box you use should crush on impact, so use a material like cardboard instead of plastic or metal. You can line a box with any cushion or soft material, such as foam, sponges, bubble paper, cotton or marshmallows.

The solution is to use a cube shape as the core to hold the egg. The longest will be the one holding the force when it hits the ground. When only one straw is bearing the force, most of the force moves along the direction of the straw, thus little goes to the egg. One thing we noticed was when the egg dropped to the ground, the side that landed on the ground was on 3 straws with the same length sticking out the 3 vertexes.

Students must determine how to spread out the force over time and redirect the impact of the force so that the egg itself does not directly hit the ground. The key to a successful egg drop container is providing room for the egg to move and to absorb some of the force within a soft environment that will not crack it. In this activity, your students will get to do all of that as they are challenged to protect an egg from breaking after it is dropped from a set height. This activity is part of the Incredible Egg series of activities, which are designed to be done during the Spring. Looking for more ideas that incorporate parachutes in your egg drop challenge? Place the egg in a red Solo cup with some cushioning (shredded paper, cotton).
Straws are lightweight and flexible to absorb the force of the drop, but they have high axial strength to support the egg and hold their shape. Slowing the egg's fall is key for keeping the egg in one piece, but slowing does not take the place of protecting. This means that, if you create a parachute for the egg, you still need to protect the egg.
Monkey thought she could create a little nest for the egg like in a hot air balloon. She used the trash bag as the balloon and placed the egg in a plastic ice cream dish. In this version, I challenged the kids to create a cage for their egg out of straws. Create a protective shell for the egg using paper mache. The hardened shell provides a protective barrier against impact.
Don’t assume others’ successful ideas will automatically work for you. One of the sources we get our idea from is this Egg Drop Design YouTube video. The guy in the video made it look so easy to use a straw structure. However the key is to think through the reasons behind each design and analyze the causes of failure or success.

Have students hypothesize whether the eggs will break based on how much water is in the bag. Sometimes having limited materials brings out students’ creativity. Give students nothing but an egg, paper, and scissors, and see what they can come up with. Place a heavy rock in the bottom of the first cup (the rock should be heavier than the egg). Then, put six more cups on top, put the egg into the seventh cup, and cover the stack with the eighth.

How Do Cotton Balls Prevent an Egg From Breaking?
Attach a parachute made from a plastic bag or thin fabric to slow down the descent of the egg. The egg is almost sure to survive if you cushion it appropriately and slow its fall enough at the same time. It's possible to do this in many ways, and it may take some creativity to find the best way based on your resources.
If you have any bubble wrap around the house, wrapping the egg in several layers of bubble wrap should also provide a good cushion. Your students will use readily available materials to build a device that can protect an egg during a fall. Egg drop contests frequently reward students whose eggs survive drops from the highest height.
Then long straws are glued along each side of the cube. We made sure that each long straw extends out of the cube vertexes at a different length. Gravity is a force of attraction — it pulls on a mass, which is how much “stuff” something is made of. Earth’s gravity pulls on you and keeps you on the ground; it also holds the atmosphere and the moon in place. When you drop your landing craft, gravity pulls it to the ground. Future Engineers hosts online innovation challenges for K-12 students.
If you don’t have floam, you can also try kinetic sand, play dough, or anything that will cover the egg and absorb the impact. She padded the egg in several layers of padding, including a plastic bag blown up to create an air pocket. Here are 10 simple egg drop design ideas for kids to try. We have two versions of this egg drop challenge below, one for older kids and one for younger kids.

Some competitions limit the materials you can use, and it also takes creativity to work within those requirements. These questions have had high school physics students pulling all-nighters for decades. Luckily for the generations to come, our good friend former NASA engineer Mark Rober is here to enlighten you.
You can also try tying several balloons to your egg before dropping it instead of building a parachute; they should slow the egg's descent. Aerodynamic rotors, such as those on a propeller beanie, can also work. The weight of the egg actually makes the rotors spin faster to slow its fall. If you make the rotors just the right size, the egg may fall slowly enough to survive, even without added protection. Looking for tried-and-true ideas for the parachute egg drop method? Give students a variety of materials—straws, Popsicle sticks, paper, bags—and see who can make a parachute that helps the egg float instead of splat.
