Spooky Expanding Ghost Balloon


  • Empty water bottle
  • Balloon
  • Small funnel or piece of paper rolled into a cone!
  • 1 tbsp baking soda
  • 1/2 cup vinegar


  • Pour 1/2 cup of vinegar into an empty water bottle.
  • Place the funnel into the open end of the deflated balloon and pour in the baking soda.
  • Secure the open end of the balloon onto the top of the bottle, being careful not to dump the contents of the balloon into the bottle quite yet.
  • When you're ready, hold the balloon upright allowing the baking soda to fall into the bottle and mix with the vinegar.
  • Watch the ghost grow!
