Frequently Asked Questions
Q1: Can I use any type of milk for this experiment?
A: Yes, different types of milk will yield varying results. Whole milk and heavy cream generally produce the most vivid colors due to their fat content.
Q2: Is there a substitute for dish soap?
A: Dish soap is essential for this reaction. However, you could try hand soap, but results may vary.
Q3: Can I reuse the milk for another experiment?
A: It’s best to dispose of the milk after the experiment as the colors can start to blend and lose vibrancy over time.
Q4: What happens if I stir the milk?
A: Stirring will mix the colors together, but you’ll lose the spectacular swirling effect! It’s best to observe until you’re satisfied.
