We did two bottles of diet coke first and then a bottle of root beer and then coke. The first bottle of diet coke was absolutely spectacular! I took a video of it so I have no photos of it, however I believe the diet coke reached a height somewhere between 8 or 10 feet. The second bottle of diet coke was good but not as good as the first, partially, I think, because half of the mentos ended up on the ground rather than in the soda.
Second diet coke. As you can see, the shapes the exploding soda took on are really, really cool! I've never been this excited about diet coke before!
I want to do more of these for two reasons, the first being, it's just fun to turn a 2 litre bottle of soda into a geyser, and two, I think it would be cool to get some super closeup photos of the soda as it erupts.
How many other sodas have any of you tried it with? Sprite/diet? Dr. Pepper/diet? Ginger ale/diet? Diet root beer? Mountain Dew/diet?
