Cool Science Experiment

Double Replacement Reaction00:01:15

A double replacement reaction is performed using potassium chromate and silver nitrate, resulting in the formation of a red precipitate identified as silver chromate.

Water Bottle Crush Experiment00:02:03

An experiment demonstrating air pressure involves attempting to crush a water bottle, followed by using ethanol and fire to create a vacuum inside the bottle. The combustion process creates heat, expelling air molecules. Sealing the bottle results in the external air pressure crushing it.

Combustion Byproduct00:03:25

The combustion inside the bottle leaves water as a byproduct, along with carbon dioxide. This demonstrates the products of the combustion process.
