Balloon Ghost Science Experiment

Want to show your students what happens when baking soda and vinegar mix? This simple Halloween activity is a great way to talk about chemical reactions, plus it’s safe and not super messy. Grab your materials and set this up during a fall festival or outside for a fun science experiment.

Supplies Required:

• white and orange balloons
• funnel
• black sharpie
• plastic water bottles
• vinegar
• baking soda

Balloon Ghost Science Experiment: How to

Draw ghostly faces on your balloons to start. Use the funnel to add some vinegar to an empty water bottle. You only need a half a cup. Then, use the funnel to add baking soda to the inside of the balloon. Add a couple of tablespoons. Attach the balloon to the top of the water bottle without dumping any of the baking soda into the liquid yet. Once you are ready, let the kids dump the baking soda from the balloons into the water bottles and watch as they fill with air! The kids will be amazed.
