An amazing discovery happened when people added rubber bands to devices with wings on them. With special components that attach these parts together which make things fly! With the idea of birds wings in mind, humans have invented amazing technology that has changed lives of people all over the world. The aeroplane was amazing that adds jet propultion to wings that are like birds wings. The structure of these wings when moving through air makes what ever they are attached to move upward due to how it pushes through the air. It is actually lifted instead of it magically flying. There are always physics involved in our world with amazing inventions that use physics to defy gravity. The twisting of rubber bands causes them to twist and stretch which influences propelling and whatever they are attached to, will spin with it, causing movement to happen depending on the functions of their attached parts.
