They are primitive type of artificial light.

Galvanic fluid under pressure is forced through a very fine wire which is thus heated and emits light, this may be lit without the use of matches, a great convenience in extensive premises.

The fine wire is enclosed in a glass globe to protect it. When this wire breaks, the whole globe must be discarded and replaced with a new one.
The man has a supply of these globes but does not know if they are used up and useless, or new ones.
He is shaking them and looking at them in the hope of determining which ones are good.
It would be more sensible to discard used up globes promptly, they are useless and there is no merit in keeping them.
New globes should be kept to hand, and left in their paper wrappers until needed so as to not be confused with old ones.
Spare globes come in many different types according to the pressure and the quantity of galvanic fluid that they are intended for, also different types of connection exist.
It is most important to keep spare globes of the correct sort for your premises.

Producing ones own galvanic fluid is a costly and complicated procedure, it is better to obtain a connection to the town lighting works if available.

He's giving it a shake to see whether the capacitor has blown in the cheap LED light he got from B&Q?

Galvanic fluid is colourless, weightless, and hard to detect. Without the incontrovertible evidence of a lit lamp that never needs any oil or other fuel, one might doubt the existence of this fluid.

Babies are a gift from god, and are delivered by midwives.
