The bright flash occurs because when sperm enters an egg it leads to a surge of calcium which triggers the release of zinc from the egg. As the zinc shoots out, it binds to small molecules which emit a fluorescence which can be picked up by camera microscopes.
Shibori is a Japanese technique of creating designs in dyed fabric. It is a dye-resist technique, using items that bind the fabric to create areas where the dye will not penetrate. Depending on the materials used and how the fabric is bound, the dyed designs vary from random splashes of color to highly symmetrical patterns.
Shibori is the Japanese art of shaped resist dyeing. The fabric is compressed by using wrapping, stitching or folding techniques that create a resist when dyeing the fabric; that is, the âresistâ creates areas where the dye is not absorbed into the fabric.hibori is the Japanese art of shaped resist dyeing.
