All balloons filled with helium can float. I'm married and want to float on the wedding table. /kloc-Can aluminum balloons under 0/0 inch float with helium?

At present, the basic size of the aluminum foil ball that can float is 18 inch, and a Japanese 16 inch aluminum foil can also float, which is the minimum size. If it is smaller, it will be too heavy to hold too much helium, resulting in too much buoyancy for the spherical skin to float. I am a professional balloon maker, I dare not say how authoritative the answer is, but this is experience ~ ~
