1) What wax are you using?
2) Where did you learn the routine?
Well I just came up with a good routine for it but I only have wax from spun and the like. Hard and not too sticky.
I will be working with Ammars routine so I think I will be using his wax as Dave said.
I'm going to interpret "I just came up with a good routine for it" to mean that you haven't really studied any professional instruction, just basically figured out a handling and started throwing decks at the ceiling.
There's a lot more to it that the basic concepts of simply controlling a card, getting wax on it, and flinging the deck at the ceiling, which is why I asked those questions. It was possible that you had the right wax (or a usable wax) but didn't have the knowledge, or vice-verse.
Ammar is the way to go. His teaching of the Card on Ceiling is the best that I've come across. It's very thorough, and I recommend it highly. All the detail is there... not just the card handling, but also things like acquiring and prepping the wax, correct sizing of the wax ball, applying the wax, banding the deck, the proper tossing technique, prop management, choosing the right ceiling, etc. Although you can find the routine on EtMCM v5, get Ammar's standalone package, as it includes his wax.
BTW, generally speaking, dental wax is a pretty good substitute for magician's wax, and I do use it for some things. While it might be an okay
choice for Card on Ceiling, it's not the best
choice for Card on Ceiling. As DaveV said, Ammar's wax is the best... hands down.
