so i'm trying to do a science project, they're making you do a research paper on two topics. anyway one of my ideas was to make a backpack that gives you good support and makes your load feel light no matter how much you put in. I was thinking that...Sounding a little crazy but, finding a way to somehow opposing gravity’s pull on the backpack. somehow acting like a balloon. i have no clue how to do it. but i feel like saying that is a bit much. why do i always have to procrastinate.
