The audience is invited to play a guessing game - strange shots are revealed to be of a gasometer.
A cinematic guessing game.
Intertitle reads: : "Here's a strange looking object .... try your skill and guess what it is ....." Top shot of a large circular area with lots of people moving around on it. Intertitle informs that it is a gasometer bottom - the largest in the world - with 233 men operating the screws which lower it to the foundations.
Another top shot with the men all in place then a shot of the men operating the screwing mechanisms in synchronisation. Shot from below of the framework of the gas tank. Men walking along the very top of the scaffolding. One man does acrobatics on the framework. Houses are visible a very long way below.
Quite a strange little film.
