- 1 tablespoon white or cider vinegar
- 2 tablespoons baking powder
- 1 tablespoon cornflour
- 1 teaspoon glycerin
- 2 drops food coloring

Mix the vinegar and baking powder together in a small bowl; add the corn-flour and glycerin when the baking powder stops foaming. Stir in the food coloring and add water if the solution seems too stiff. Store in a tightly covered jam jar or plastic container.
