Floating Ice Cube Weeping Tears
Description
A fascinating experiment demonstrating the physical properties of ice when in contact with oil and other liquids. We observe how variations in density and states of matter cause the ice cube to float while shedding "tears" of water that gather at the bottom of the vessel. Witnessing this unique melting process reveals the captivating interplay between different substances under the influence of gravity.

קוביית קרח מרחפת ומזילה דמעות
ניסוי מרתק המדגים את התכונות הפיזיקליות של קרח במגע עם שמן ונוזלים אחרים. נבחן כיצד שינויי צפיפות ומצבי צבירה גורמים לקוביית הקרח לצוף ולנטוף "דמעות" של מים הנקווים בקרקעית הכלי. הצפייה בתהליך ההפשרה הייחודי חושפת את יחסי הגומלין המרתקים שבין חומרים שונים בהשפעת כוח הכבידה.

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
