Part 2/10:
Paul begins by explaining his initial steps in preparing the surfactant solution. He adds 100 mL of water into a container, then incorporates a surfactant, carefully placing the lid on and shaking it to mix. Noticing excessive foam and bubbles—which can interfere with the plating process—he references instructions advising the use of less surfactant. Since he had already used a set amount, he compensates by diluting the mixture further with an additional 300–350 mL of water.
