Mentos Geyser Car – 12 Days of Wonder

By Blog Editor Susan Wells

We have reached Day #9 in our 12 Days of Wonder. Today’s spotlight science toy is Geyser Car.

Steve Spangler Science is celebrating the 12 Days of Wonder and highlighting our top 12 science toys and kits that are perfect to put under the tree. As blog editor, social media coordinator and mom of two budding scientists, I will share my review of each product. Steve Spangler Science also found 12 respected, popular mom bloggers to each test and review one of our 12 science gifts. I will include a link to their blogs and their honest reviews of each gift idea at the bottom of this post. Today, Sarah from Moose Tracks and Tater Stacks shares her review. The kit is also the Deal of the Day. So check our blog every day for the next few weeks to learn all about our 12 Days of Wonder.

Day 9 of the 12 Days of Wonder features the Geyser Car.

Today only, this kit is our DEAL of the Day for $12.50. Regular price is $24.99.

My Review: 

I brought the Geyser Car to our Thanksgiving dinner. It served as our after dinner entertainment.

Boom Splat Kablooey – Steve Spangler Science and Klutz Team Up to Create a New Experience for Kids

Little known fact… I love to juggle. Better known fact… I’m not that good, but that’s not a reflection on my teacher – a great book called Juggling for the Complete Klutz. This was my introduction to Klutz Press some 30 years ago – an amazing company with a vision for really innovative product. So, when I was invited by the editors of Klutz to be a contributor to their latest book – Boom Splat Kablooey – I was thrilled. The book is scheduled for release in the next few weeks… but readers of this blog can purchase a copy from our store now.

Boom Splat Kablooey author Pat Murphy wanted to use our Geyser Tube toy as a trigger device for the perfect soda geyser, but she wanted young readers to experiment beyond the popular MENTOS® version. What if you want to test other materials like rock salt, sand, pepper, marbles… whatever? That’s the question that Klutz posed to us when we began development on the Geyser Tube Depth Charge. After lots of testing and lots of geysers going off,

Steve Spangler Science Sets New Guinness World Record at 9News Colorado Rockies Science Day

World’s Largest Physics Lesson

We’re honored to get to say, “We did it!” With a final count of 5,401 people, all armed with Windbags, the seats at Coors Field were flooded with science as we set out to set a new world record for the the Largest Physics Lesson.  What a sight… a sea of Windbags with a special fly-over by Sky9, that captured the moment on film from the helicopter.  The requirement for Guinness World Records was that the lesson last at least 30 minutes, but, we decided to take it to the next level and go for a full 51 minutes.  There were Mentos Geysers, Rockies players with Potato Guns, a lesson on Bernoulli’s Principle, and, of course, a giant kaboom for the finale. And, at the end of the lesson an official Guinness World Records adjudicator was on hand to present our team with a certificate for the new world record. Learn more about all of the science experiments featured on Science Day at Coors Field.

Mentos Geyser Tube Crosses the Border

A few months ago, I had the pleasure of meeting Dave Reed, the VP of Technology for eSpeakers, at the Winter NSA Conference in Orlando.  Dave talked to me about the work he is doing in Mexico with his family and I gladly passed on a few science gadgets to take back to his home in Ajijic, Mexico.  As it turns out, the Mentos Geyser Tube™ is a hit in any country!  Dave sent me an email recently and let me know that his 10 year old son, Riley was the hit of his school’s science fair.  Dave was even kind enough to send some pictures of the Geyser Tube in action with his son.

I love hearing stories about how making science fun can overcome all boundaries, even those between countries!  Thanks Dave for the great follow-up and congratulations to Riley… keep up the great work and happy experimenting!

Mentos Geyser Tube Featured on Food Detectives

Ted Allen, host of Food Detectives on the Food Network, featured a segment using our Mentos Geyser Tube toy as a trigger device for their exploding soda segment. The producers did a nice job of explaining the science behind the eruption and even shared a cool variation of slowly lowering several Mentos into the bottle using a piece of wire. The demo showed why the Mentos have to quickly sink to the bottom of the bottle if you want to get a huge eruption. In their explanation, the microbiologist expert said that diet soda is used because the aspartame weakened the surface tension of the liquid which aided in the eruption. However, we know from experimentation that regular soda works well, too. Does regular sugar also weaken the surface tension? Dropping Mentos into plain seltzer water produces almost no eruption. Does this suggest that the surface tension of the liquid is higher in the plain seltzer water than it is in regular soda or diet soda?

You see… that’s why the Mentos soda geyser keeps showing up time and time
