The first time I saw this, I thought you cut the video when it turned black/blue.

Could you imagine seeing this for the first time. OMG I want to see this happen, in like a 30 gallon tank ;)

@mrhomescientist Exactly what i figured, cool

The cloudy precipitate @ 8:20 is manganese hydroxide or carbonte depending on what you've used to neutralize the mixture.

What happens if you don't stir the reaction with a stir bar?

Can the Sodium Thiosulfate be the pentahydrate, because that's all I can seem to find easily. Or is that what you're using anyway?

@hayjude99 Yeah that's all I use. You're just mixing it back into water anyway, so anhydrous is unnecessary.

Can the malonic acid be substituted with any other more easily available acid? Also does it have to be KIO3 or does KI suffice?
Anyway, really awesome video.
Thanks!

@Oskar3855 Hey sorry for the slow reply. I don't think any of those substitutions can be made. According to the paper I list in the description, you need malonic acid and at least the iodate ion. Feel free to experiment though, there's a couple different versions of this experiment!
