Liquid Crafting is the use of non-solid material in textile crafts. Common examples are jelly yarn and liquid filled vinyl tubings.
In BIT.FLOW Julius Popp pumped color-coded liquids through an arrangement of clear vinyl tubings, thus creating interesting visual effects.
The Institute For Figuring features under-water corals that were created using Jelly Yarns.
The first occurence of liquid crafting probably goes back to 2002, when Laura Splan used her own heart as a liquid pump, creating a beautiful red scarf.
