Frankenstein Foam: Baking Soda and Vinegar Science Experiment
Decorate a clear cup with a Frankenstein face, then create a crown of bubbly green foam using baking soda, liquid egg whites, food coloring, and vinegar.
Yield: 1 experiment cup
Equipment
- Clear 16 oz. plastic cup
- Black permanent marker
- measuring spoons
- measuring cup
- Fork or spoon
- Small cup for the measured vinegar
- Rimmed baking tray
Materials
- 1 tablespoon baking soda
- 1½ tablespoons liquid egg whites
- A few drops green food coloring
- ¼ cup distilled white vinegar
- Googly eyes
- Craft glue for attaching the eyes to the outside of the cup
Instructions
- Draw Frankenstein hair, eyebrows, a stitched mouth, and stitches on the outside of the clear cup.
- Glue on the googly eyes and allow the glue to dry.
- Place the decorated cup on a rimmed baking tray.
- Add the baking soda, liquid egg whites, and green food coloring to the cup. Stir together with a fork or spoon.
- Measure the vinegar into a separate small cup.
- When everyone is ready to watch, pour the vinegar into the Frankenstein cup. The reaction starts immediately.
- Watch the foam rise above the rim. Leave the cup on the tray as the foam eventually slumps and spills down the sides.
Notes
- Amounts are for one cup.
- Use liquid egg whites, as used in the successful test.
- For multiple cups, prepare each mixture separately and add the vinegar to one cup at a time.
- Craft glue belongs only on the outside of the cup.
- This is a science activity, not a food recipe.
