Frequently Asked Questions:
Q1: Can I use anything besides dish soap?
Yes, you can try other liquid soaps, but ensure they are not overly thick or gel-like as they may not whip well.
Q2: What if I don’t have a mixer?
A hand whisk can work, but it may require more effort! You can also use a jar with a lid and shake vigorously.
Q3: Is it safe for young kids?
Yes, but always supervise young children during the activity to ensure they don’t ingest the mixture.
Q4: How do I store leftover foam?
While it’s best fresh, you can store it in an airtight container for a short period. Just be mindful it may lose some texture.
