Today, we will be making perfumes! Perfumes are a combination of natural scents, human-made chemicals, and alcohol. They are designed to leave a pleasant smell on your body!
When you spray perfume, scent molecules float in the air and enter your nose. Inside your nose, special olfactory receptors, which allow you to smell, detect these molecules and send signals to your brain.
Creating perfume is a chemical experiment. Different molecules mix and interact in oils or alcohol. Some molecules evaporate faster, some slower, changing the scent over time. This is why a perfume smells different when you first spray it and after a few hours.
