Whistler is a level in the video game World of Goo. It is the seventh level of Chapter 2. The player must use the whistle and the weight of some Dark Black Goo to reach both some sleeping Water Goo and then the exit pipe.
Use what's mentioned above.
It's a little luck based, but remember that where the Balls go is influenced by both the whistle's x and y positions. If you bend it over to the left to pick up the Water Goo and then move the cursor right, the Goo may stay on the left side because the cursor is too low.
