The variables in a blobs in a bottle experiment may include the type and amount of materials used to create the blobs, the size and shape of the bottle, the temperature of the water in the bottle, and the amount of time elapsed to observe the blobs forming and reacting. These variables can be manipulated to study how they affect the formation and movement of the blobs in the bottle.
The density of blobs in a bottle would depend on the material the blobs are made of and how tightly packed they are inside the bottle. The density can be calculated by dividing the mass of the blobs by the volume they occupy in the bottle.
