Watch the myth-busting explosive science experiment videos below and follow along with the Experiments Worksheet or experiment questions below each video.
Recommended Grades: All
Suggested Printout: Experiments Worksheet so you can follow along and answer the experiment questions. The experiment questions are also listed below each video.
Experiment #1: Baking Soda Volcano
Baking Soda Volcano Experiment Questions:
- What are your predictions? Size, color, time duration of eruption, etc.
- If we add more baking soda OR more vinegar will the explosion change?
- What if we add more of both?
- What are your observations of the reaction?
- Pause after Priya asks how long you think the reaction will go on for. How long do you think the baking soda will react with the vinegar? Were you close to the real time?
- Give a summary in your own words of the reaction of baking soda and vinegar:
- Pause after the second question is asked. If we add more baking soda OR more vinegar will the explosion change? What if we add more of both?
- What is the reactant that is used up first in the reaction called?
- How can you make your reaction bigger? (by adding more of what ingredients)
Experiment #2: Soda and Mentos
Soda and Mentos Experiment Questions:
- What are your predictions for this experiment (color, time and size of reaction, etc)?
- Why do you think this reaction happens?
- Do you think the reaction would work with any liquid or only coke?
- What did you observe on the reaction?
- Give a summary of the science behind the reaction in your own words:
- Pause after the second question is asked, do you think you can do the reaction twice with the same coke?
- Why do most people prefer diet soda when performing this experiment?

The University of Texas’ student chapter of the American Institute of Chemical Engineers (Texas AIChE) was founded in 1941, with a goal of connecting and empowering the whole Chemical Engineering community through numerous professional, social, service, and academic events. We aspire to be the hub of Chemical Engineering at UT Austin, providing students with the resources and events that will allow them to excel during their time at the university and beyond.
