The Mystery of the Linked Balloons: How Is This Possible?
Description
What happens when you connect a tube between a fully inflated balloon and one that is only partially inflated? This surprising experiment demonstrates the relationship between the air pressure inside a balloon, its surface tension, and its radius of curvature. The results reveal why air flows from the small balloon into the large one, defying our initial intuition.
Original title
חידת הבלונים המחוברים – איך זה יכול להיות?! #3
מה קורה כשמחברים צינור בין בלון מנופח מאוד לבלון מנופח חלקית? הניסוי המפתיע מדגים את הקשר שבין לחץ האוויר בתוך הבלון לבין מתח הפנים שלו ורדיוס העקמומיות, ומראה מדוע האוויר זורם דווקא מהבלון הקטן לגדול ולא כפי שהיה ניתן לצפות באופן אינטואיטיבי.

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
