Singing Bowl 59 May 3 2014
Description
A fascinating physics demonstration of a Tibetan bowl filled with water, which produces resonant sounds accompanied by ripples and sprays when its rim is rubbed. The phenomenon occurs due to resonance and standing waves, which transform the mechanical energy of the friction into visible vibrations that agitate the water's surface, causing it to "dance.
Original title
קערה מנגנת 59 (3.5.2014)
הדגמה פיזיקלית מרתקת של קערה טיבטית מלאה במים, המייצרת צלילים המלווים באדוות ובנתזי מים בעת שפשוף שוליה. התופעה נוצרת עקב תהודה וגלים עומדים, ההופכים את האנרגיה המכנית של השפשוף לתנודות ניכרות לעין המרעידות את פני המים וגורמות להם לרקוד.

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

Floating Paintings
Credit: מכון דוידסון לחינוך מדעיDiscover how to bring your drawings to life using nothing more than a whiteboard, water, and an erasable marker. This experiment demonstrates the unique properties of dry-erase ink, which is insoluble in water and does not adhere strongly to surfaces. This lack of adhesion allows the drawing to detach in one piece and float on the water's surface, powered by the force of buoyancy.4:09

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
