The shoe boot is a popular project for high school, high school and college students, and also for amateurs. This is my best attempt. I have encountered many challenges throughout this scientific project. I have added some of my failed experiments at the end of my writing project. At the beginning of the project, he hoped to invent a shoe loader to charge a smartphone. After many failed attempts, my new target was changed to power the smaller iPod for 2 seconds. However, it was a fun project and I learned a lot from him. Saving the world is not an easy task; We need a breakthrough in smart materials.
