The creator introduces the project of making a thermometer. He lays out the necessary components: a clear plastic bottle (e.g., a water bottle), rubbing alcohol, food coloring (blue is shown), a drinking straw, and modeling clay. He also presents a Taylor brand store-bought thermometer for comparison and calibration during the experiment.
Goal: Gather all necessary components and understand the basic principle of a thermometer.
