![]() ![]() The prompt for our assignment stated that due to habitat loss, possibly caused by climate change, Madagascar is experiencing a severe protein deficiency among various highland villages. Once back in class we did not just implement ANY egg drop challenge, but the Air Dropping Nutritional Resources in a Remote Area in Madagascar Egg Drop Challenge ! We toured the facility, ideating about the possibilities of prototyping our products, ooh-ing, and ahh-ing at the projects we saw engineers and entrepreneurs working on. The workshop is full of metal cutting machines, woodworking stations, welding stations, laser cutters, and sewing machines. ![]() The Tech Shop is the world’s first open access, Do-It-Yourself workshop built for rapid prototyping. Products and Services class learning about prototyping at Tech Shop SF. During our second San Francisco residency, Sustainable Products and Services students visited the Tech Shop and participated in a PGS tradition, the Egg Drop Challenge to practice what we learn in the course – rapid prototyping. Things that squish could include bubble wrap, fabric, cardboard, paper scraps, airbags, straws that break etc.The purpose of the Sustainable Products and Services course is for students to create a business to practice the entrepreneurial process of innovation, development, and commercialization of new products or services. It takes energy to deform a material, so the more material you can put in front of the egg to absorb the kinetic energy through deforming the better chance you have of your egg surviving. What is one big way to absorb a lot of kinetic energy quickly? When it stops suddenly you need to absorb all of that kinetic energy (the energy of movement), ideally not into your beautiful pristine egg. Just before the egg hits the ground it is moving fairly quickly. You also want to think about how your egg will be buffered. If your egg drop experiment has protection on only one portion of the egg, you need to make sure there is a way to guarantee how the egg will descend to the ground as you are leaving yourself exposed. Drop it on its side or its top/bottom with no protection and it will break. A successful egg drop project means your egg has no cracks on it whatsoever when you take it out. ![]()
