You’ll Need
  • Baking soda, vinegar, balloons, food colouring
  • Tape, yarn or string, small lightweight toys (“bugs”)
  • Plastic cups, spoons, markers
Experiments
  1. Bubbling Pumpkin Potion: Add baking soda and coloured vinegar to a small pumpkin “cauldron” and watch it fizz! Talk about carbon dioxide bubbles forming.
  2. Dancing Ghost Balloons: Mix baking soda and vinegar inside a bottle with a balloon on top. Watch your ghost rise as the gas fills it!
  3. Spooky Web Challenge: Build a spider web from tape or yarn and test which “bugs” stick. Adjust your design — can you make it stronger?
Talk About It
  • What made the bubbles or the balloon move?
  • What materials made the best spider web?
  • What do you think would happen if we used more vinegar or longer strings?
Reflection
  • Encourage your child to describe what they observed — colours, sounds, movements.
  • Ask: “What surprised you the most?” or “What would you try next time?”
