I believe that gravity can't hold down everything like balloons.
Also you have to think about the science of it all i mean if we didn't have gravity we would be drifting of into space right now. Also when someone is jumping or jump roping like this.
Or even an animal has gravity just like this cute little fury one right here.
Once things go up they just fall right back down like when me and my friends are jumping on a trampoline. It looks fun and it is fun just look at these kids. Also every time they go up they fall back down. See some are up in the air and some are down and thats how gravity works.
