A representative symbol of chemical experiments, test tubes are made of special glass for accurate experimentation. They are designed to withstand high temperatures and chemical reactions, and are a fundamental tool for lab safety.
Recently, the test tube emoji has become frequently used on social media as a symbol of science. It's especially common in STEM education or science-related content and has become a popular icon among science experiment YouTubers.
