The other half are made by combining molecules of other vapors into larger "clumps"-a process called nucleation.
For aerosols to form, the bonding particles must cross an energy threshold, which the scientists call nucleation barrier.
It works through a process called nucleation, whereby the carbon dioxide in the soda is attracted to the tiny bumps on the surface of the mints.
According to Hyneman (he's the mustachioed MythBuster), it's a process called "nucleation," in which the particular chemistry of the Mentos candy interacts with the chemistry of the carbonated Diet
Apart from the major disruption in flight traffic and the economy, the Icelandic volcano eruption promises in the short-term to disrupt upper atmospheric circulation patterns and temperatures, with an additional impact due to sulfuric acid "nucleation" and subsequent acid rain.
This forming of ice crystals is called "nucleation".
"nucleation," in which the particular chemistry of the Mentos candy interacts with the chemistry of the carbonated Diet Coke, causing the carbon dioxide gas, or CO2, to suddenly come out of suspension in the liquid and make a break for freedom.
Scientist had originally predicted that the millions of tons of newly formed carbon dust particles would be ideal nucleation sites for raindrops.
The mountains are believed to have been a key nucleation point for the vast East Antarctic Ice Sheet.
The crystals themselves become nucleation sites for the crystals to grow.
