The Paralyzed Finger Experiment May 3 2015
Description
Discover how anatomical limitations in the tendon structure of the human hand affect finger mobility. This fascinating experiment demonstrates why it is so difficult to lift the ring finger when the middle finger is folded, revealing the shared mechanical connection between the two. Gain a deeper understanding of the hand's structure through a simple and surprising exercise that proves not everything is under the brain's direct control.
Original title
ניסוי "האצבע המשותקת" (3 במאי 2015)
גלו כיצד מגבלות אנטומיות במבנה הגידים של כף היד משפיעות על יכולת התנועה של האצבעות. הניסוי המרתק מדגים מדוע קשה להרים את הקמיצה כאשר האמה מקופלת, וחושף את הקשר המכני המשותף בין השתיים. היכרות עם מבנה היד דרך התנסות פשוטה ומפתיעה שמראה שלא הכל נמצא בשליטת המוח.

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
