Here's the ChUcK method for easy multi-color dyes.
Basically, when you're adding in the color later, make sure you balance your 4oz flint bottle of heavily concentrated blue acetone in a precarious manner by the edge of the sink. There's no need to be uber-cautious and actually place the bottle INSIDE the sink (stainless steel sink, in case you were wondering. Just thought I'd point that one out).
Next, wait until you are almost done with Tim's TickRex-X. At the Penultimate moment, completely spazz out. I recommend for this a grand-mal seizure, but you don't want it to last too long. Really, just long enough to knock the bottle of dye all over the countertops and floor.
I know what you're saying. You're saying to yourself, "Oi! Right in the nadgers! I'll bet his fiancee's pissed! I'll bet that 86es ChUcKdyes for a good while!"
Well, you're correct on all 3 statements.
So, without further ado, here's the last one for the time being:
Sorry again, Tim!
