No, it wouldn't work the matteral is too heavy
helium is lighter than air
That would be Helium
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Balloons are full of a gas called 'helium', which is lighter than air. The helium is trapped inside the balloon, that's what makes it float.
Fill a balloon part way with helium, make an animal out of it and have it float.
helium is lighter than air
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
NO! Footballs are not full with helium because if they were they would float up in the sky
That would be Helium
Helium is light and it will float / rise.
100% helium
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
Helium is lighter than air. so balloons filled with helium will float in air
No, human body doesn't float on helium as it is light.
If you want the balloons to float, you would probably use helium.
No, because the density oh helium is bigger (x 10).
