Mentos Fun

We did a little experiment today.

Plop seven mentos into two liters of soda, and you get a fizzy little geyser of fun.  Ah, but which fountain would spout higher between Sprite, Coke and Diet Coke?  Let's find out:

To measure the geyser height, we used good ol' math.  The white board behind the bottle has two blue lines on it.  The distance between said two lines is 50cm.  So we took the photos, counted vertical pixel span between the blue lines, and used that number to translate the geyser height in pixels to centimeters.  I could have used feet and inches, but F that.  Metric people.  Metric!

Anyway, after all the pixel counting was over, Diet Coke is the champion!

The left over amounts are not quite accurate, as the kids drank some when I wasn't looking.

We were going to go to the store to get more soda for experimentation, but then someone ran over our test rig.  Oh well.
