Explanation:
The balloon has to displace some air, so in response, the air pushes up on it. ... But hydrogen is less dense than air, so the air pushes up on the balloon harder than gravity is pulling it down, and the balloon tries to move up! So just like wood float on water, hydrogen balloons float on air.
