Intern Gets a Little Wet While Launching 700 Mentos Diet Coke Geysers at NAEYC 2008

It's tough to really demonstrate the Mentos Geyser Tube in an exhibit hall filled with teahcers... until we created the Mentos Geyser Chamber. It's a plastic box that measures 4 feet square and 7 feet tall. It's the perfect enclosure to launch off a few hundred Mentos Diet Coke geysers. The only other thing you need is someone to stand inside the box for a few hours. Most of the time, Drew Vriesman is an undergraduate at the University of Colorado, Boulder, studying marketing. But when he puts on his intern hat at Steve Spangler Science, he's never quite sure what to expect. Drew Vriesman and Taylor Marsh took turns launching geysers at the NAEYC 2008 conference in Dallas. Combined they launched 700 erupting Diet Coke geysers using over 4,000 MENTOS® Chewy Mints. The interns spent about 20 hours in the Geyser Box over three days and entertained (or amused) about 15,000 teachers who stopped by the Steve Spangler Science booth.

Mentos Geyser Used to Launch Beaker 20 Feet

It was quite a week for our Spangler Science team when we invaded Texas with 24 staff members and Spangler Ambassadors. Half the team headed to Fort Worth for CAST (the Conference for the Advancement of Science Teaching) and half the team went to Dallas for NAEYC ( the National Association for the Education of Young Children). While our NAEYC team was launching Mentos geysers on the Boy in a Box, the CAST team also found a unique way to use the Geyser Tube... launching our favorite scientist, Beaker , 30-feet in the air in the Geyser Chamber. It was quite a sight at the Spangler Science booth when Beaker when shooting through the air on a stream of Diet Coke. When the team wasn't launching stuffed Muppets, they were busy talking with excited science teachers and even presenting workshops at the conference. Spangler Speaker Julie Gintzler presented her Chicka, Chicka - KABOOM workshop. The eager participants were more than a little excited when Julie pulled out the amazing Square Bubble and the "magical" Spot Dot Thumb... now there's way … (more...)

Having a Blast at the NAEYC 2008 Conference

If you attended the annual NAEYC (National Association for the Education of Young Children) conference last week in Dallas, Texas, it wasn't hard to find the Steve Spangler Science booth. All you had to do was listen for the shouts of surprise as we launched over 600 Mentos Geysers with the Geyser Tube™ in our own take on the classic dunk tank... the Boy in a Box. It was great to see the teacher reactions when they pulled the string and sent a blast of Coke raining down on our never-tiring Boys in a Box.

As my team can attest, I lost my voice at the conference... just like I do every year... from explaining to everyone who passed by the science behind the Mentos and Diet Coke reaction.  It's important as educators that we don't just drop some Mentos in a Coke and call it science.  The resulting geyser is a great effect, but you are missing the key piece of the lesson.  Shoot off a geyser, then listen as your students start to ask questions... "Why does that happen?"...  "What if we used more Mentos?"...

Science “Left Behind” in American Schools

You may have seen the recent commercials showing a child raising flags representing America's standing in school ranking world-wide. I came across an article for the same campaign that shared some striking, but unfortunately not surprising, statistics. According to the "One Nation Left Behind" program, 20 countries outscore the US in science education and 93% of US middle school teachers have little or no science training. As standardized testing becomes key in schools nation-wide, the decline in science education becomes widely apparent. The Strong American Schools Website offers more staggering statistics and eye-opening quizzes that help drive home the point that our children are not receiving enough science education. Check it out and be prepared for some shocking results. However, the One Nation Left Behind campaign is committed to creating awareness about the growing education problem in America... from science, to math, to English.. and offers opportunities to get involved in your community.

Going Green and Plastic Free

The BBC UK called our offices yesterday to get permission to use the Inside the Soda Can experiment, that I've done on 9News, for Chris Jeavans "plastic-free" blog. Chris is trying to live for one month without using any plastic products. As the soda can experiment proves, Chris is finding that this may be a harder task than she once expected! When you perform this experiment, you will find that aluminum cans actually have a plastic liner, which prevent the acid in pop from eating away at the metal can. Mark that up as one more product Chris will be eliminating from her life this month! Be sure to check out Chris' blog for some great info on what it means to "go green" in this consumer-driven world. It's always fun to see our experiments making it around the world.
