If you are curious about the history of organic go here to read more. Origami is the Japanese art of folding paper into 3 dimensional shapes without the use of cutting. It’s a variation of the more well know paper folding art technique of origami. Kirigami is the art of folding and cutting paper. Depending on the type of pigment based ink used ,solvents may include rubbing alcohol or ammonia based chemicals. That is why the black details sketched in Micron and Sensei pens remain unchanged when exposed to water. The black markers are pigment based and cannot be dissolved by water. Water based inks like those found in our Koi markers are dissolved by water, hence water is the solvent. Solubility is defined as the is the ability of a substance to be dissolved by a solvent. When the flower is placed in the water the ink is dissolved by the water and flows both through the paper to the white wide AND out of the paper and into the water, leaving a trail of ink behind. The water based inks in this project are also moving when exposed to water but they move by diffusion- the movement of particles from an area of high concentration to an area of low concentration. Just like a wilted plant expands and perks up when it is finally watered, the fibers in our paper flowers swell and expand when placed in water, causing the flower to open!ĭiffusion is very similar to osmosis but osmosis refers strictly to the movement of water. Since paper is made from wood fiber, when it is placed in water it absorbs the water until it every fiber is wet. The process of osmosis continues until the water has reached a state of equilibrium. Plants absorb water through a process called osmosis, this is the movement of water across a membrane from an area of high concentration to an area of low concentration. Paper is made from trees (wood) that has been ground into a pulp and dried. Let’s Talk STEAM The Science Absorption and Osmosis
