It seems like I've spent an hour on this, but it's probably more like twenty or thirty minutes.  ;D  Anyway, I breezed through the first two islands, collecting a bunch of OCD finishes along the way, but this one has me stumped.  No matter how I try to build to the pipe, the last ball catches on first and destroys my whole structure.  Once I got one of the black balls into the pipe during the half second or so before that last ball was destroyed, but surely that's not how I'm supposed to win?  What am I missing?  The sign says that "some types of balls are more flammable than others", but the only type I can use is the red balls.

You must release the white structure up above by burning the red goos holding it. Red goos will be collected and enter the pipe on fire.

but when you burn those red goos, the white structure swings to the left falling away from the pipe, plus the white structure get's destroyed and spread into several white goos

is not that i want to get the game solved here in public, but i'm really stuck on this  :'(
