How to pierce a balloon without popping it: two methods
Description
Discover how to slide a skewer through an inflated balloon without popping it by applying the principles of polymer structures. This experiment demonstrates the elasticity of rubber chains at points where tension is lowest. The demonstration also offers an alternative method using adhesive tape to modify the surface properties of the balloon, illustrating how physical reinforcements can prevent structural failure.

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
