Lacrosse is a contact team sport played between two teams using a small rubber ball (62.8-64.77 mm, 140-147 g) and a long-handled stick called a crosse or lacrosse stick. It is often considered as a rough sport, although injuries are less frequent than in American football and other contact sports.
Section I: Body Casting Alginate Alginate is a temporary, highly absorbent, biodegradable skin safe mold making material made from algae. It is a powder that when mixed with water will set to a firm yet rubbery consistency. Alginate takes impeccable detail from skin and castings are incredibly life-like. Fibergel: designed with fibers mixed into the alginate. It is used to mold objects with severe undercuts where strength and shrink resistance is needed â Set time: 4-5 minutes. Section II: A Word About Mold Making and Casting Mold Making and Casting are not entirely exact sciences.
To be truly biodegradable, a substance or material should break down into carbon dioxide (a nutrient for plants), water and naturally occurring minerals that do not cause harm to the ecosystem (salt or baking soda, for example, are already in their natural mineral state and do not need to biodegrade). leaf is a perfect example of a biodegradable product -- it is made in the spring, used by the plant for photosynthesis in the summer, drops to the ground in autumn and assimilated into the soil to nourish the plant for the next season.
