Liquid and Solid Starch Solutions
Description
Discover the fascinating world of non-Newtonian fluids through a simple experiment using a solution of cornstarch and water. The video demonstrates how this substance changes its viscosity based on the amount of force applied to it—flowing like a liquid when handled gently, yet becoming as rigid as a solid when subjected to a sudden hit or rapid pressure.

חומר שהוא גם נוזל וגם מוצק - תמיסת עמילן
גלו את עולמם המרתק של נוזלים לא-ניוטוניים באמצעות ניסוי פשוט עם תמיסת עמילן תירס ומים. הסרטון מדגים כיצד החומר משנה את צמיגותו בהתאם לעוצמת הכוח המופעל עליו, כך שהוא נשפך כמו נוזל אך הופך לקשיח כמו מוצק בעת חבטה או לחץ מהיר.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
