The video helped! Here, in order, are what I think I saw:
1. Sparks too far away - re-watch where it ignites - your sparks were right in it only on that attempt.
2. Not fluffed up enough
3. Need more sparks - try pressing harder against the wheel. Try thumb instead of finger.
I'll dig one of mine out and try to re-create the situation, but honestly, I never have any problems with this. I'll edit this after I try it out and tell you what my experience is.
