This dramatic chemistry demonstration makes a liquid appear to transform into water, wine, milk, and beer as it is poured from one glass to another. The sequence involves pH indicators, precipitate formation, and gas release, illustrating multiple chemical concepts in a visually striking way.

1. Fill a “water” glass with distilled water and add sodium bicarbonate solution.
2. Add phenolphthalein drops to an empty “wine” glass.
3. Place barium chloride solution in a “milk” glass.
4. Put sodium dichromate crystals in a “beer” glass and add hydrochloric acid just before the demo.
5. Pour the liquid from the water glass into the wine glass (it turns red).
6. Pour from the wine glass into the milk glass (it turns cloudy white).
7. Finally, pour from the milk glass into the beer glass (it turns amber and frothy).

• Use sodium carbonate instead of sodium bicarbonate for a stronger effect.
• Replace sodium dichromate with yellow food coloring for a safer but less vivid beer color.

• Wear goggles, gloves, and a lab coat throughout.
• Handle hydrochloric acid carefully - it is corrosive.
• Barium chloride is toxic; avoid contact and inhalation.
• Sodium dichromate is highly toxic and should only be used by trained chemists.
• Dispose of solutions in chemical waste containers following local regulations.

• What causes the red wine color to appear? (Phenolphthalein indicator turning pink in basic solution.)
• Why does the milk stage turn cloudy? (Formation of insoluble barium carbonate precipitate.)
• What produces the bubbles in the beer stage? (Acid reacts with carbonate to release carbon dioxide gas.)
• How could this demonstration be adapted to use only safer household materials?
