Can a inner tube from a motorcycle filled with helium float into the sky?

inner-tube would probably be too heavy, the total weight including inner-tube and the helium must be less than the weight of air that would occupy the same space.

Helium loft is 1 gram/liter. A heavy rubber inner tube won't get off the ground.

I haven't tried it but I believe the innertube is too heavy.

You would find that there is not enough gas capacity to offset the weight.

Imagine a heluim filled balloon. It has much greater gas capacity and is much lighter (thin material, light weight valve).

These things barely float. It takes many hundreds to lift 150 lbs.

It might hover a bit, but I seriously doubt you would get much loft. If it was incredibly thin walled, it might go up a little. Condoms work waaay better

no. the weight to lift is too one sided.

yes

yes hold on
