This is what I imagined "doing science" to be when I was a 5 year old, and it's fantastic. This brought a genuine, mirthful smile to my face. Thank you, good sir.

@Wofflebot

That was made even more impressive by the reaction occuring during the pour

@saltedcaramel7809

I love the highly accurate  measurements like "a bottle" or "a bunch"

@DoFliesCallUsWalks

Making part B before part A is the most nilered thing ever

@davidmarshall6970

Timing the color change with pouring out the solution was an excellent choice. That looked unreal

@OldChannelLightniteProductions

I remember someone once saying “magic is just science we haven’t discovered yet”

@digital_pocket_watch

So you're telling me that if I swallow disinfectant, vitamin C, and corn starch, and some water, I can become a wizard?

@nateharvey1300

“next we need to make part A”
immediately cuts to a bottle with a huge “C” on it
lol

@shubhadabangale5172

We learned this under chemical kinetics... and the whole classed erupted in a spontaneous WHOA!!! when the teacher portrayed it. 
Leaving this comment here so that I can recall those times I enjoyed practicals with no stress...

@Comfymura

Ah, yes. Blinker fluid.

My granny told me, if you want to take iodine spots from clothes ( as kids we had scratches all the time and mom will put iodine to heal the wounds) thus we had spots everywhere). She took lemon and potato to rub it into a spot, it turned potato blue, they you wash it easily. Thank you for bringing back memories))

@SnyperMK2000JclL

In this day and age if I didn't know any better I'd say that was some slick CGI, but I really enjoyed and excelled in chemistry and I've done those cool color flipping experiments before. Super cool!

@NotNotGrumm

oversimplified analysis if anyone's wondering: 

This is caused by the fact that there is 2 reactions happening at the same time. One that creates iodine (I2) and one that instantly reduces it. After a while, a threshold is reached where there is more I2 being created than there is reducing agent left in the mixture, and the I2 is able to exist long enough to react with the starch, creating a very distinct blue color. As long as it is well mixed, the entire solution will reach this threshold simultaneously.

@kala5882

I like the subtle humor of first making part B, and then making part A, the first ingredient of which comes from a bottle with a big "C".

@ginassi_

This reminds me of titration 😩💕 truly the most enjoyable part of any chemistry project.

@RealPhoenixFlight

Its stuff like this that makes me question “Who the hell discovers this??”

@marooon9814

Fun fact! I also crush up vitamin C tablets to add into shampoo when I want to fade away my semi-permanent hair dye!! Crazy how well it works

@dan725

I love how one can just use stuff we can get from Walgreens and do this at home with some coffee filters with our kids. This was such a lovely video to engage families to showcase chemistry.

@vinyashere4all

That reaction totally blue my mind!

@sparkyheberling6115

First dissolve the cornstarch in a little cold water. Before blending in the boiling water, give the cornstarch slurry another stir. No lumps, no straining.
