How to Flip an Open Can Without Spilling 3 (2015-05-03)
Description
This is a demonstration of a simple physics experiment that shows how air pressure acts on liquids inside a can. Using nothing more than a single sheet of paper, an open can full of water can be turned upside down without its contents spilling out. This is made possible by the force exerted by atmospheric pressure pushing upward against the paper from below.

איך להפוך פחית פתוחה בלי שהיא תישפך? - 3 (2015-05-03)
הדגמה של ניסוי פיזיקלי פשוט המראה כיצד לחץ האוויר פועל על נוזלים בתוך פחית. באמצעות שימוש בדף נייר בלבד, ניתן להפוך פחית פתוחה המלאה במים מבלי שהתוכן שלה יישפך ארצה, בזכות הכוח שמפעיל הלחץ האטמוספרי על הנייר מלמטה.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

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
