As the world of technology rages on, it is important for new products to be able to keep up. In the video “Making Stuff Smarter,” David Pogue, the host, explores the ways scientists have changed everyday products to make them more efficient for practical use in the world. For example, materials that can heal themselves are currently developing based off …show more content…
In the video “Making Stuff Stronger,” David Pogue explores the various types of strength in a material and how scientists can change the amount of it. Scientists can strengthen either a material’s compressive strength, tensile strength, or toughness. In addition to that, they can also create entirely new materials for real world purposes by altering the chemical structure. One example of this is a synthetic polymer with very high tensile strength and toughness called Kevlar®. Soldiers wear it as part of their uniforms because it is a tough “shield” against bullets. However, Kevlar® is not the absolute strongest material. Other scientists have discovered how nature produces strong materials, such as a toucan's beak or spider silk. By studying the natural world, our world can now grow carbon nanotubes and make artificial spider silk by genetically engineering goats to produce milk that contains spider silk
