Bowl Riddle Solution (Plus 2 BONUS riddles) ft. Kurt Hugo Schneider part 2/3

Noooooo!!! The inverted cup!!! I excluded this solution because for me it was somehow cheating, using a tool... I would have used the vortex instead. The only requisite for the vortex to work though, is that the water level must be low enough not to spill from the sides of the bowl. For the broom riddle I think the shorter end has to be heavier to compensate the higher momentum due to gravity of the far end of the longer stick.
