A layer of milk curd was formed by boiling milk until only vapor pockets remained. Droplets of red food dye were then added.

Dry ice in a dyed water-alcohol mixture sublimates into fog-filled bubbles.

Subliming dry ice creates a buoyant plume of CO2 gas, which drives recirculation in an emulsion of blue clothing dye and vegetable oil.

Dry ice in a water-alcohol mixture bubbles up in a fog that spills over a surface.

Flow circulates rapidly on the surface of bubbles, visualized by iridescence caused by light wave interference.

Lights reflect on “Boo Bubbles”, fog filled soap bubbles that rest on black velvet without popping.

Boo Bubbles”, filled with CO2 and water fog, are heavier than air.”
