Zero density means there is nothing at all. Nothing means no foam, as foam is a solid with bubbles, and bubbles are small enclosures surrounded by a material barrrier that delimits the extent of said bubble.
So, you cannot make zero density foam.

Basic arithmetic:
Zero times anything is zero.
Zero density = zero foam.

The lowest density solid you can make is an aerogel, consisting of very low-density silica foam. If it was filled with helium during manufacture, it would float in air. But the helium would soon diffuse out. I've heard of meringues baked in a helium-filled oven floating in air. You bake them with a string attached so you can tie them down.

You cannot have any physical material of zero density.

If it was zero density it would practically be nothing and would float away.
