Combine 10,000 hydrogen bubbles with a lightning spark, and you get a very impressive combustion, as our high-speed cameras show.

The oxygen of the water fuels the exothermic reaction, leaving hydrogen bubbles which causes the compound to foam.

When submerged in water, hydrogen bubbles almost unnoticeably begin to form on the surface of the metal-though if powdered, it reacts much more rapidly.

The hydrogen bubble and its release and subsequent ignition inside the containment placed other systems at risk.

On the third day following the accident, a hydrogen bubble was discovered in the dome of the pressure vessel, and became the focus of concern.

Immediate steps were taken to reduce the hydrogen bubble, and by the following day it was significantly smaller.

Attempts have been made to make simple cells self-depolarizing by roughening the surface of the copper plate to facilitate the detachment of hydrogen bubbles.

Or having another electrode already making a stream of hydrogen bubbles in the same bath.

With both this method and the tellurium method, it is important that hydrogen bubbles should not be produced.

With a higher current, hydrogen bubbles will form on the item to be plated, leaving surface imperfections.
