@stridek12: There's a secret hiding on this paper…but you won't see it until the chemistry works its magic. 👀✨ Try this Invisible Handprint #ScienceExperiment with just a few kitchen ingredients and learn how pH indicators work! Materials needed: • Turmeric • Baking soda • Warm water • Hand sanitizer (enough for a paintable consistency) • Paintbrush • Paper Turmeric contains curcumin, which changes color when it reacts with bases like baking soda. This pH reaction turns the invisible handprint into a visible surprise! ⚠️ WARNING: Turmeric can stain surfaces and clothing, so protect your workspace! #ScienceTok #STEM #Chemistry
