Wacky Lava Lamps!
Question:
Out of water, Diet Coke and prune juice which liquid will produce the most entertaning lava lamp?
Hypothesis:
We think that Diet Coke will be the most entertaning because the carbonation of the Diet Coke combined with Alka-Seltzer will make bigger, better and best bubbles!
Procedure:
There are no special needs for this experiment. |
The Science behind it
If you look at the ingredients for Alka-Seltzer, you will see that it contains citric acid and sodium bicarbonate (baking soda). When you drop the tablet in liquid, the citric acid and the baking soda react, creating bubbles of carbon dioxide. The scientific formula is: H3C6H5O7 (citric acid) + 3 NaHCO3 (sodium bicarbonate) = CO2 (carbon dioxide) + H2O(water) + Na3C6H5O7 (trisodium citrate). The carbon dioxide creates big, fun bubbles.
Those bubbles move the liquid (water with food coloring, prune juice or Diet Coke) up to create the lava lamp effect.
Those bubbles move the liquid (water with food coloring, prune juice or Diet Coke) up to create the lava lamp effect.
Conclusion
In conclusion, we discovered that Diet Coke works the best because it has the most bubbles. When the Alka-seltzer is added, the carbon dioxide from the Alka-Seltzer combines with the carbon dioxide in the Diet Coke and more bubbles are created, making a great lava lamp!
