Mentos Geyser experiment challenge

JMJ 34  *Everyone should try the Mentos Geyser experiment in their backyard, no matter what age!  Go grab some Diet Coke and a pack of Mentos mints, follow the video instructions at, and run away from the eruption.  This is a science experiment filled with awesomeness.

Ring the School Bell 34/180 days

The early a.m. today was consumed by science and Halloween party preparations.  Melissa and Sabrina enthusiastically spent a large portion of the morning working on their history/science fair projects.  This year, Melissa has decided to go with a Mentos geyser experiment, which involves combining Diet Coke (unless you want a real sticky mess with regular Coke) and a Mentos mints.  Not sure who came up with that one, but it can shoot up a geyser 20 feet high.  According to the Steve Spangler website,

“The reason why Mentos work so well is twofold—tiny pits on the surface of the mint, and the weight of the Mentos itself. Each Mentos mint has thousands of tiny pits all over the surface. These tiny pits act as nucleation sites—perfect places for CO2 bubbles to form. As soon as the Mentos hit the soda, bubbles form all over the surfaces of the candies and then quickly rise to the surface of the liquid. Couple this with the fact that the Mentos candies are heavy and sink to the bottom of the bottle and you’ve got a double whammy. The gas released by the Mentos literally pushes all of the liquid up and out of the bottle in an incredible soda blast.”

Now that is cool science.  Everyone should try this one at least once in your lifetime! For more of the fascinating science behind this experiment, click the link or cut&paste this into your browser:

Mentos Geyser Trials- Don’t forget to run away from the eruption!

          Sabrina, meanwhile, worked on her own project, a historical account of the eruption of Mount Vesuvius that destroyed Pompeii.  Curiously, our science gal Sarah, elected not to participate in the history/science fair this year, and spent the morning working on the Halloween party decorations instead.  I was actually thankful, because a lot of preparations needed to be done.

Halloween Party Prep

          Melissa, Sarah and I headed out to the California Science Center around noon, for yet another visit this school year.  They had a workshop to attend, appropriately titled “The Physiology of Fear.”  My intentions had been to wander around the beautiful USC campus while they were in class.  However, the 2½ hours were responsibly spent, on my part, in the Science Center cafeteria, writing business checks for John, tallying business deposits, and correcting the kids’ schoolwork.  For 2 1/2 hours.  I seriously underestimated the amount of time this would take. Maybe next time I’ll get to sit by one of the university’s lovely fountains and contemplate life…  The drive back home was treacherous.  A usual hour drive, extended to over two hours.  I stopped halfway to preserve my sanity, and we ate burgers at a West Coast favorite, In and Out burgers. After I arrived home, a friendly chat with my sweet friend Veronique, finally revived my energy levels.  All-in-all, a great day.

** Note to the Reader- Today’s narrative is part of our family’s school journey from a few years ago, during my eldest daughter’s senior year in high school, a rather emotional year, with its many ups and downs.  Every day’s blog entry coincides with a day from that special year.  It can be read from the beginning by selecting the “Ring the School Bell 180” category on the side bar.  Commence with the narrative, “The School Bell- What comes to mind when ‘you’ hear that bell?” and follow along with us day-by-day through the school year.  Hope you will join us!

May God shower blessings on your family as he has on mine.    Annette
