In the Bottle-Forbes bottle method of emulsions, what is the first step?

Explanation:
In the Forbes bottle method, you start by placing acacia gum in a dry bottle. This emulsifying agent needs to be hydrated properly to form a smooth mucilage that can effectively stabilize oil droplets once the emulsion is formed. Adding the gum to a dry bottle ensures it disperses and hydrates evenly when water is later introduced, reducing clumping and allowing a stable, uniform emulsion to develop as you add water and then oil and shake. The key idea is to have the emulsifier ready in dry form so its hydration and function aren’t hindered by pre-wetted lumps, which is why this initial step is essential.
