My wife and children recently completed another unit study as part of their homeschool lessons. As mentioned in a prior blog post, they’ve been learning about select states within the U.S. This particular unit study focused on the state of Wyoming. Out of all the things they were taught, one of the items that the kids found most fascinating were the geysers found in Yellowstone National Park. So, in order to make the lesson more real, we concluded their studies that week by making our own “Old Faithful” using a couple of packs of Mentos, a few 2 liter bottles of Diet Coke and a cool little gizmo called the Geyser Tube. In addition to being a whole lot of fun, this experiment can be used to teach children not only about geysers, but also about chemical reactions and the power of gas pressure. It’s also messy, but we didn’t care.
We captured our backyard geyser fun on video and thought we’d share it with you by including the YouTube video found below. We hope you enjoy watching this as much as we enjoyed doing it! It was a good amount of fun and the really kids loved it, as you can tell from the background comments in the video. Enjoy!

Thanks for your comment! Our primary reason for homeschooling is the same as yours.
We’re going to add that to our “to do” list. Very cool!
I love Steve Spangler’s Geyser Tube! My kids do the Mentos Geyser thing every chance they get.
Have you thought about signing up for the Experiment of the Week on Steve Spangler’s blog? We get a free experiment in my email every week, and they all come with complete instructions, a video to watch, and all the information we need. The kids love it.
