Why we have to wait for 2 minutes before starting to count bubbles?

Waiting for 2 minutes before starting to count bubbles allows enough time for the bubbles to stabilize and form a consistent pattern. This ensures that the count reflects a more accurate representation of the bubble activity, as initial bubbles may be influenced by variations in the liquid's surface tension or agitation. Additionally, this waiting period helps in minimizing the impact of transient bubbles that may not be representative of the overall bubble formation process.
