yeah it works fine, normally i do this after crushing up a pill to snort......
ill rail half, then not feel like railing the other half so ill dump it in a glass of water.
it sticks to the sides sometimes aswell, so have another drink out the same glass, small glasses or shotties work best.
on this topic, when i did this with the YELLOW 3's....... one thing i could NOT belive was how solid that powder was, when dumped in the glass, the yellow powder would just SIT on top in a clump. even when swooshing or stirring the powder would just SIT there, it took so long to dissipate.....
