Stuck on Cut the Rope level 1-21? Here's how it's done...
1. Cut the bottom left rope - the bubble moves to collect the star on the top right
2. As soon as the star is collected cut both ropes on the right - the candy swings down and off screen to the left.
3. On the way back it collects both bottom stars and enters the bubble.
4. As it starts to float upwards cut the last rope, top left, allowing the candy to float into Om Nom's mouth.
Done... Now watch the video
