Call now for a limited edition engraved bar of soap with each building you coat.
Personally, I've always wanted a wall that would be controlably "sticky." Handy for putting up diagrams, printouts, pictures etc.
This tech also appears to function as a large area, controlled volume fluid pump for dispensing very small fluid volumes. This is *exactly* what is needed to supply some of the active heat shield ideas for reentry vehicles.
Of course the $64 is what happens to the surface tension forces if the flow is contaminated (IE soap) or airborne particles get into the layer.
