“Happy Clouds” by Stuart Semple
London artist Stuart Semple uses soap and helium to create floating foam clouds in the shape of smiley faces:
The machine he uses makes a lighter-than-air foam using glycerin, food dye, and helium, and extrudes cakes of it through a die to create floating foam happy faces, which he releases into the air 2,000 at a time.
The world needs more random cool stuff like this.
