So it was all quiet in the Aspen Center for Physics offices.
Why? Tuesday family picnic outside…!
Was it quiet out there? No! There were science experiments with the food of course!
How did they get the diet cokes to erupt like that?
The instigator of this was Phenomenologist Josh Erlich, who is shown holding the secret ingredient… a common sweet/candy you can probably buy in the same place you got the diet coke…
Know what the secret ingredient is? (I’ve blotted it out with green paint. [Update: I’ve added a new image (left) with the secret ingredient -mentos- revealed]) And do you know why it works? Tell us! (If you already know the answer -having heard it elsewhere- and don’t have to figure it out, then wait a while and let others guess or work it out.)
