The Levitating Can: From Cup to Cup
Description
A simple kitchen experiment demonstrates how air pressure allows you to bounce an empty can from one cup to another. By blowing forcefully into the gap between the cup and the can, high pressure is created underneath the can, pushing it upward and allowing it to "hover" through the air.

הפחית המרחפת: מכוס לכוס
ניסוי פשוט במטבח המדגים כיצד לחץ אוויר מאפשר להקפיץ פחית ריקה מכוס אחת לשלוף אותה אל כוס שנייה. על ידי נשיפה חזקה ברווח שבין הכוס לפחית, נוצר לחץ גבוה מתחת לפחית שדוחף אותה כלפי מעלה ומאפשר לה "לרחף" באוויר.

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
