Which Carbonation Keeps Its Bubbles The Longest

The Objective

I tested whether liquid carbonated with dry ice keeps its bubbles longer than pre-carbonated water bought in a store or liquid carbonated with carbon dioxide in the form of a tablet. I hypothesized that liquid carbonated by dry ice would keep its bubbles longer than store bought pre-carbonated liquids or liquids carbonated with carbon dioxide tablets.

Methods/Materials

To test my hypothesis, I compared the time in which water carbonated with dry ice kept is bubbles to water carbonated with carbon dioxide tablets and pre-carbonated water.

I repeated the experiment seven times.

Results

I found that water carbonated with dry ice kept its bubbles an average of 4 hours and 27 minutes.

In comparison, pre-carbonated water kept its bubbles an average of 3 hours and 32 minutes and carbon dioxide tablets kept its bubbles an average of 3 minutes and 42 seconds.

Conclusions/Discussion

I concluded that liquid carbonated with dry ice kept its bubbles the longest.

Which type of CO(2) carbonation keeps its bubbles the longest when added to liquid?
