How to Build a Trash Bag Hot Air Balloon
Description
Discover how to build a simple homemade hot air balloon using a lightweight plastic bag and birthday candles. This breathtaking experiment provides a hands-on demonstration of the principle of buoyancy, illustrating how hot air is less dense than cold air, causing it to rise. It is highly recommended to perform this experiment at home only under adult supervision and while strictly adhering to all safety guidelines.

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
