Talk About It
  • As your child watches the reaction, give them time to observe before explaining anything.
  • You might notice excitement, surprise, or repeated requests to “do it again” — this is curiosity at work.
  • Use simple language and follow their lead. If they ask questions, explore together rather than giving quick answers.
  • Ask: What do you think will happen before we add the vinegar?
Extension Ideas

Try adding the vinegar slowly and then all at once. What changes?
