Level 34 help needed!

I know I'm pathetic!! Can't work out how to burst the black bubbles on this level. Help greatly appreciated.

You can't burst the black bubbles. You have to get to the lightning bubbles -- preferably without popping too many poison bubbles along the way (because each poison bubble that pops takes away 3 of your bubbles to shoot).

Try to clear the ice bubbles using only the color that is NOT the same color as the poison bubbles closest to the ice bubbles. You can just "throw away" any bubbles that aren't the color you want.
