Let's start this blog by going through a fun experience :
Do you know that if you insert a Mentos to Cola, bottle will explode? Just try it, it's amazing. Really!

"If you drop a pack of Mentos into a bottle of Diet Coke, you get this
huge fountain of spray and Diet Coke foam coming out," says Tonya Coffey,
a physicist at Appalachian State University in Boone, North Carolina.
"This was a good project for my students to study because there was
still some mystery to it."
What is the explication of this phenomenon?
As stated actors from MythBusters, so the potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos, all contribute to formation of the foam.
The structure of the Mentos is the most significant cause of the eruption due to nucleation. When we have a fruit-flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas mint-flavored Mentos (with no such coating) added to carbonated drink formed an energetic eruption, affirming the nucleation-site theory.
According to MythBusters, the surface of the mint Mentos is covered with many small holes that increase the surface area available for reaction (and thus the quantity of reagents exposed to each other at any given time), thereby allowing CO2 bubbles to form with a rapidity and in a quantity that are responsible for the "jet"- or "geyser"-like nature of the effusion.

So much for the theory of how it works. The length of the throw even held competitions and we even recorded a world record of 2,865 simultaneous geysers. At the end of the article still see how it looks in practice.

Do you think it can be dangerous for children ??
ReplyDeleteNo this is possible only, if you drink full of bottle. Mayby you a little bit inflates
