A helium-filled balloon is less
A helium-filled balloon is less dense than air and it can float upwards. When the balloon is shrunk by pouring liquid nitrogen over it, it becomes denser than air and falls to the ground.
Upon warming and expanding, it will fly up again.This video is produced in Singapore. More videos on www.plenrich.com
