![]() As we learned in geometry, 3 points form a plane, this means the landing force are equally distributed among the 3 straws, and then transfer to the crossing straws connecting these 3. Because, with this core shape, the landing side is usually with 3 straws sticking out. We analyzed the causes again, and realized that pyramid is not a good shape to start with. Second Egg drop design with Straw – Unbalanced Pyramidīased on the learning from the first failed experiment, we did a 2nd design to make sure all extension straws sticking out of the pyramid vertexes with a different length. With this realization, we started the next design. These parallel straws must have hit the egg hard. This makes the connecting straws parallel to the ground. 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. After the failure, we discussed the reasons.
