The Glucose Geyser

During a low yesterday,  I made a discovery.  You see, at Company X, we have refrigerators full of free carbonated water.  I typically am not a fan, but we have the stuff laced with fruit essences so I can tolerate it from time to time.  Anyway, so I was low and was munching on a dry and chalky glucose tab, and I felt the need, as I often do, to chase the tab with a swig of water.  Not thinking, I grabbed for a newly opened bottle of lime flavored carbonated water, lifted it to my lips and poured back a sip.  To my surprise, my mouth was instantly full of trillions of tiny carbon dioxide bubbles threatening to explode all over my keyboard.  I manage to keep from spilling and, like any good scientist, decide to check for reproducibility.  Another glucose tab, another swig, another near explosion.  Those of you who regularly consume carbonated beverages may not be surprised by this, but I, who rarely drinks anything but cold water or hot Earl Grey tea, was quite pleased with this new discovery.

So, what are we going to do with this new information? I suggest, a Glucose Geyser (!).  In lieu of adequate outdoor space where messes can be easily cleaned, I have not yet tested my theory, but I expect the situation to play out like this:

Supplies:

2L bottle of carbonated water or other carbonated beverage(anything unsweetened is best for ease of clean up)

6 glucose tabs (preferably of a diameter that will fit easily though the beverage lid)

index card

glucose tab tube, uncapped

Instructions:

  1. Fill the glucose tab tube with glucose tabs, set the index card on top and invert.
  2. Open the 2L bottle and position the glucose tab tube/index card above the opening such that the index card is the only thing separating the tabs from the liquid.
  3. Have spectators stand back (or not if they don’t mind getting a bit wet) then quickly remove the index card so the glucose tabs quickly drop through the opening into the bottle and quickly step back.
  4. Watch as the glucose tab provides a site of nucleation for the carbon dioxide that is dissolved in the liquid causing the liquid to erupt from the bottle with gusto.

At least this is what I hope happens.  If it doesn’t, just replace the glucose tabs with mentos candies.  Or watch this video.

Speaking of Geysers, I am adding in a shameless boast about the vacation M and I just got back from:  Yellowstone is AMAZING! Geysers around every corner! Seriously great vacation. Good on BG lvels too, especially when you utilize some of the less traveled back country trails.  Yay for vacation!

If you try my little experiment, please let me know how it turns out!
