Won’t they feel me pushing their hand?

The first thing to be said is that you are not looking for a direct movement. That is, the intention is not to end up with a hand in front of their face, which you simply push forward. That provides too much movement for your partner to resist against. Instead, aim for more circular movements. This is one of the reasons that we prefer the falling hand, as the hand goes up and over and then down onto their face. The less direct movement gives less cause for resistance.

Nevertheless, the second thing to note is that they will only object to you pushing their hand if they don’t want it to happen. So, if you have given them no idea that their arm will move, if they sensed you pushing their hand they might object. Or, if you have implied that their hand will move all on its own, if they feel you pushing it they may conclude that you are trying to fool them.

So, this is only an issue to be concerned about if your actions do not match your words. After all, if you look at the fast hand variation, the hand is very much pushed right up to their face. If you move smoothly, explaining what will happen – and what is happening – then this is not something you need to excessively worry about.
