Elephant Toothpaste Reaction Explained
A step-by-step 3D lab simulation shows yeast catalyzing the decomposition of hydrogen peroxide into water and oxygen gas. Soap traps the released oxygen bubbles, producing a rapid foam eruption from an open bottle, colored green with food dye. The animation highlights catalysis, gas production, and exothermic reaction cues, making it useful for students learning about reaction rates, catalysts, and decomposition reactions in an engaging, visually clear format.

The prompt that made it
Create a professional educational 3D chemistry laboratory simulation on a completely clean white background. Scene 1 — Laboratory Setup: Show a small transparent plastic bottle standing upright and completely open, placed in the center of a large clean laboratory tray. Next to the bottle, show two small transparent laboratory cups. Scene 2 — Preparing the Hydrogen Peroxide Mixture: Pour approximately 30 mL of 6% hydrogen peroxide (H₂O₂) into the open plastic bottle. Do not fill the bottle; keep it mostly empty to allow the foam to expand safely. Add a small amount of liquid dishwashing soap to the bottle and gently swirl the bottle to mix the contents. In a separate small cup, add one or two drops of green food coloring and mix it with a small amount of the soap-and-hydrogen-peroxide solution. Show the liquid becoming bright green. Scene 3 — Preparing the Yeast: In the second small cup, combine a small amount of dry baker's yeast with a small amount of lukewarm water. Stir thoroughly until the yeast is evenly suspended in the water. Clearly label this cup: “Dry Baker’s Yeast + Lukewarm Water” Scene 4 — Starting the Reaction: Carefully pour the yeast mixture into the open plastic bottle containing the hydrogen peroxide, dish soap, and green food coloring. Immediately show the reaction beginning. The yeast acts as a catalyst that rapidly decomposes hydrogen peroxide into water and oxygen gas. Scene 5 — Foam Formation: Show a rapid production of oxygen bubbles inside the soapy liquid. The bubbles become trapped by the dish soap, producing a large amount of thick foam. The foam should rapidly rise out of the bottle and expand upward and outward into the large tray. The foam should be bright green, thick, bubbly, and continuously produced for several moments. Final Scene: Show the bottle surrounded by a large mound of bright green foam overflowing from the bottle and spreading safely inside the tray. Use a close-up shot to clearly show thousands of small bubbles forming inside the foam. Scientific Explanation: Yeast contains the enzyme catalase, which catalyzes the decomposition of hydrogen peroxide into water and oxygen gas. 2H₂O₂ → 2H₂O + O₂↑ The dish soap traps the oxygen gas in bubbles, creating the large amount of foam known as the “Elephant Toothpaste” effect. Visual Style: Ultra-realistic educational 3D chemistry laboratory simulation, realistic liquids and foam physics, accurate laboratory equipment, clean white background, professional scientific presentation, smooth camera movements, soft studio lighting, high detail, no people, no cartoon style, no explosions, no fire, no unrealistic effects. Add clear on-screen labels: “Hydrogen Peroxide — H₂O₂ (6%)” “Dishwashing Soap” “Green Food Coloring” “Dry Baker’s Yeast” “Lukewarm Water” “Catalyst: Catalase” “Oxygen Gas — O₂” “Elephant Toothpaste”
