I am lighter than air but a hundred people can't lift me What am I?
The answer is a balloon. Balloons are lighter than air due to the helium or hydrogen gas they are filled with, but even with a hundred people, they cannot be lifted due to their buoyancy and the mass of air displaced by the balloon.

What is lighter than air but can be never lifted?
A common answer to this riddle is "a bubble." Bubbles are filled with gas, making them lighter than air, but they cannot be lifted in a traditional sense because they are delicate and will pop if disturbed. Another interpretation could be "thoughts" or "dreams," which are intangible and can't be physically lifted despite being considered lighter than air conceptually.

Is there anything lighter than air?
yes, anything with a lower atomic number would be lighter, for example, helium is lighter than air, which is why balloons float when filled with helium... the lighter substance rises above the heavier....
