The cores also contain microscopic bubbles of air captured in the snow before it turned to ice.
Pumping of microscopic bubbles into the water moving past a hull also causes a dramatic reduction in drag.
Charged particles create an ionisation track, around which the liquid vaporises, forming microscopic bubbles.
Void formation, where microscopic bubbles are introduced into a media by high intensity laser irradiation.
My suspicion is that Skade first created a microscopic bubble, probably sub-atomic, certainly no larger than a bacterium.
A few years back, investors were flocking to a new medical technology involving microscopic bubbles called liposomes.
One result is that the latest version, alive with palate-refreshing microscopic bubbles and tasting slightly of apples, shows more finesse than the first.
But a container of liquid with only microscopic bubbles can superheat dramatically.
I find his interest in exotic, microscopic bubbles rather gratifying.
A tiny piece of heating wire is used to boil just enough of the water to create a single microscopic bubble.
