How helium balloons work?? Posted By : Lilly Thomson

Something that is implausibly neat about helium balloons is if you procure one at the circus or fair and if you hold its string, it will ride along over you. If you permit to let the string go, it will take off until you cant spot it anymore. If we wonder why balloons fly away when we let go off them, the answer that comes is law of buoyancy.
