Odd question....

[Poolnerdgrandma]

So, my postsurgery knee is still pretty swollen, and after a very active week, we decided it would be best for me to take it REALLY easy this weekend. I tell you this in explanation and a transparent bid for sympathy, so no one yells at me.
Well, the kids want to come over, and Granna never says no to that, and we need to test the water and heat the spa.
Have I mentioned that all pool maintenance is Granna's job? So Hubby gets a water sample and brings me the kit so I can do the testing sitting down. PH high, Clorine high. Not surprising.
I decide to heroically put everything away myself, and rather than carry the case, two full test vials and the sample water back, I dump both (pink/red) vials of water back into the test water. I know, probably a bad idea, but it's done.
Here's my question: how bad a thing was it? The reason I ask is that red + red made GREEN. I haven't taken chemistry since a below par high school class. (Math and physics were my jam.)
Is this something I could do again and show the grandson? (At three, he counts the drops and notes the color change when I test)
Again, before the scolding begins, please remember I'm INJURED.

Just dispose of the mixture. Nothing harmful is involved - though I would not drink the mixture.

So I can show little guy that red+red=green?

Sure. It is just reactions to acid/bases in the sample.

Now go order some finger paints and finger paint paper for you and little man to play with OUTSIDE. Give him a dollop of each color in little apple sauce cups. Have him use his pointer fingers to get a dab of each color then mix them together on the paper. Let him explore the color changes. I am SURE he will end up with MUD in the end as they tend to mix ALL of the colors together.

Once he gets a bit older you can have him explore what happens when he goes 2 to 1 of the different color to show how it changes the colors.

We've done that, and he loves it! He started with mud, but has done red+yellow=orange, etc. Which is why I would love to blow his mind with red+red=green.
