Do you think the 'accident move' is still effective?

I’m thinking about impressing or at least getting the attention of this guy(single guy) with using some move they called as the ‘accident move’. I want to accidentally spill my drink on his lap and offer my help to clean it up after that. Or maybe I want to hit him while carrying a lot of stuff in my rush,say sorry and let him to help me to carry over my stuff,then I’ll meet him later,apologize for that action,and offer him a cup of coffee as the sign of my gratitude then we’ll know each other even further. Do you think this kind of method is still as effective as it used to be? Do you think that he’ll know that I did this on purpose? Is there any other ‘accident’ method that you know? Oh I feel so dirty,but I should try this.
