Very nice! Getting all the fancy stuff!
I just got a double drop checker from the swap-n-shop here, and while tomorrow will probably be my first real day to test it out (I have your reactor running tonight!
), I like the idea of having the ability to have a color comparison. Lighting of all kinds changes colors with yellow and blue being most commonly affected. With the double check, I can tell if it's the right color or not no matter what the lighting.
Will you have the second fluid (the one that's not supposed to change colors)? I was wondering where I'd get more when I ran out of what I have now.
