2dF and the Great Gum Machine

Before 2dF there was 'The Great Gum Machine'....

Mr Wonka led the party over to a gigantic machine that stood in the very centre of the Inventing Room. It was a mountain of gleaming metal that towered high above the children and their parents. Out of the very top of it there sprouted hundreds and hundreds of thin glass tubes, and the glass tubes all curled downwards and came together in a bunch and hung suspended over an enormous round tub as big as a bath.

'Here we go!' cried Mr Wonka, and he pressed three different buttons on the side of the machine. A second later, a mighty rumbling sound came from inside it, and the whole machine began to shake most frighteningly, and steam began hissing out of it all over, and then suddenly the watchers noticed that runny stuff was pouring down the insides of all the hundreds of little glass tubes and squirting out into the great tub below. And in every single tube, the runny stuff was of a different colour, so that all the colours of the rainbow (and many others as well) came sloshing and splashing into the tub. It was a lovely sight....

From 'The Great Gum Machine', Ch.20 of 'Charlie and the Chocolate Factory' by Roald Dahl.
