(simple)- How to do it. To do it you need to duck or called crouch then look straight or almost straight down and throw the snow ball. The snow ball with speed on the floor it very useful for some game modes but it will not work on anything that not flat including object the stair way look floor.

(complex)- this trick can make the snowball slide on the wall, bounce of the corners (no jumping bounce), be stuck near or on the wall, lose speed and be stuck when it lose all speed.

(more information)-The trick is not fully know since how you throwing, moving speed, what you on, the way you looking at and more make the ball go weird ways but the best way to throwing it almost fully flat like half a pinky finger at the floor and not moving. Some people think this is a hack since i be banned and kicked before doing it but it is a trick that is useful to know
