DO Try This At Home

Since I know that most of you are inquisitive and will have a hard time falling asleep tonight without knowing the answer to life's biggest questions, I will answer at least one of them today.


Which soda erupts the highest when 5 mentos candies are dropped into 2-liter bottles?

We did this experiment at Jenna's 7-year-old Scientist Party. Dressed in lab coats and goggles, she and her friends lined up on the sidewalk in front of the house while the bigger kids and I performed the experiment with:

Diet Coke (name brand)
Diet Big K Cola (Kroger store brand)
Diet Caffeine-free Big K Cola
Regular Big K Cola

I think there was a 3-for$2 sale on the Big K colas, hence the overabundance of that particular brand in our experiment. Had the Coke products not been three times the price, I would've used more of those. You can see that my love of science has its limits.
That's some Diet Caffeine-Free Big K Cola shooting more than 6 or 7 feet in the air.
The experiment was a hit, as were the others that we did at the party.
1. Clay divers who sink in a water bottle when squeezed.
2. Hard-boiled eggs getting sucked into a glass bottle.
3. Vinegar/baking soda volcano (even more cool when a cork is placed on top!)
4. Will It Float (guessing which objects float or sink)
5. Home-made slime with water, Borax and glue
6. Coke and Mentos explosions (note:to get 5 Mentos in at one time, we place them in a small tube, then placed the tube over the bottle to release them all at once. Kabaam!)
Unfortunately, we have no clue why any of the experiments work, so it's not like the children learned anything specifically scientific, but they DID learn that cool stuff happens when you try different things.
And also, there are many many ways to put an eye out.

I have to say, this sentence really resonated with me. As 'Science Dad', I've done a few things like this with my kids, but rarely have we touched on the actual scientific reasons or actually learned anything beyond "cool stuff happens". Thanks for lowering the bar for the rest of us. :)
