Help a noob grow his vine

Hey :slight_smile:

When following this tutorial http://www.local-guru.net/blog/2012/1/2/animating-a-growing-vine-in-Blender-2.6--
I get one problem.

The vine never totally disappears… It only gets very thin, and I can’t figure out why.

Any guesses based only on this information?

Thanks :slight_smile:
