That's actually turmeric indicator.
As, turmeric turns orange when it touches a base.

[Jellyfor.Tript.]

Baking soda is a base, turmeric turns red when coming in contact with base, the curcumin present in it does so. That's why the area painted with baking soda turns red

[jaivignesh]

turmeric is an indicator which changes orange to red when it comes in contact with water

[ElloriHeart]

It's just an indicator. Turmeric turns red when it combines with bases

My brain: it better not be green paint
Also my brain: it probably isn’t

[Lunaejdujf]

That is not ink it's reaction of a base on addition of turmeric
When baking soda( a base) is added to turmeric solution, it tures reddish brown. Like how it is shown in this video.
Also, i messed in some places but that's because I'm not that fluent in English

[max-trxm]

It feels illegal to be early
Edit: why are people being mean to me? Guys just stop why are you guys being mad over a text like it's not a big deal.

[GhoulehGoddess]

Not me watching this a million times and still not understanding how they got yellow and red both

[Icewind]
