The Coke and Mentos Experiment
Description
The famous reaction between Mentos candies and carbonated drinks is caused by a physical process known as "nucleation." The candy's rough surface rapidly releases the dissolved carbon dioxide gas within the beverage, creating an impressive fountain of foam and liquid. Learn about the science behind the world's most popular at-home experiment.

מה קורה כשמנטוס פוגשות קולה... (2014-05-03)
הריאקציה המפורסמת בין סוכריות מנטוס למשקאות מוגזים נגרמת בשל תהליך פיזיקלי הקרוי "התגרענות". פני השטח המחוספסים של הסוכרייה משחררים במהירות את גז הפחמן הדו-חמצני המומס במשקה, דבר שיוצר מזרקה מרשימה של קצף ונוזל. למדו על המדע שמאחורי הניסוי הביתי הכי פופולרי שיש.

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
