@historycalendar Interesting story. I knew a zoology technician at Edinburgh who was tasked to preserve the skeleton of a deceased giraffe from the zoo. She recounted its long neck draped up the stairs and wondering where to start. You may like this ... x.com/AlchemistAngus…

From Dingwall to Dundee, this @WoodBlocX elephant at @DundeeBotanics today. In 1706 a pet elephant evicted from an Edinburgh flat ended its days in Dundee after the baker below grew tired of dung in the dough. The sad tale is told here... thecourier.co.uk/fp/news/dundee…

The giraffe died in January 1488 after her head got stuck in the rafters of the barn she was held in. Panicked, she broke her neck when jerking her head too hard and died.

🦒 A Giraffe in Europe 🦒
It had been over a millennium since a giraffe had stepped foot in Europe.
In 1487, a giraffe sent by al-Ashraf Qaitbay, the Burji MamlukSultan of Egypt to Lorenzo de' Medici, an Italian statesman, to win support from the political dynasty.

Mulled wine? No, it's that other festive favourite, mulled vitriol. @iain_smellie got me a red cabbage for Christmas so I've steeped it in dilute H₂SO₄'s to find the safest extract that stores well. Hold tight for the update this time next year. #JamesWatt #GardenIndicators

The rescue poinsettia thinks it's November. Back in 2024 @iain_smellie bought a sorry looking specimen. I put a cutting in some water. It did nothing much for months then in July it suddenly shot out roots overnight and started growing new foliage. Look what appeared yesterday.

@CrocodileChemi1 @iain_smellie 😄 I'm making no rash promises...

@AlchemistAngus @iain_smellie Don’t be tempted to use it for some science! Well done!

Stem cutting plus a little rooting compound in water appeared to do nothing except occasionally shed a leaf for 8 months and then...

@iain_smellie That was it after 3 changes of water. If anyone needs 20 litres of red cabbage indicator, I know a guy...

Last week @AlchemistAngus was disposing of some well soaked red cabbage. Even after several prolonged extractions, some colour still remains. He’s now got a large stock of red cabbage indicator!

240 years ago James Watt was discovering red cabbage indicator. 420 days ago I repeated his experiments. With Watt's acidic advice, my extract is 14 months old, still works and doesn't smell (bad). Here it is at some popular pH values. #GardenIndicators twitter.com/AlchemistAngus…

If Snow White ebowed her way in for a bite of this "Scrumptious" science apple, she'd find something else got there first. The non-rotten part was delicious and the peel produced a pink extract that turned apple(ish) green in base. Lovely aluminium complex too. #GardenIndicators

Apple served with ammonia two ways:

After seeing apples in ammonia, @iain_smellie and I wondered what would happen in sulfur dioxide. Anthocyanins in the red flavylium form react with bisulfite to make colourless flavene sulfonates. SO₂ from hydrochoric acid + sodium metabisulfite (Na₂S₂O₅). #GardenIndicators

It’s the annual art exhibition at school. These are my RGB plots showing the pH profiles from 1-14 of a pink gladiolus (top left), Blackberry (top right), bright pink Busy Lizzie (bottom right) and purple pansy (bottom left). All similar, subtly different #GardenIndicators

It’s been a long time, but I’ve made a new Shinoda test video for the @Gardenindicators YouTube channel. This one features onion skin, the outer part so very easy to extract. youtu.be/HF94JGwLaEw?si…
