If it's five people throwing them, they're terrorists. If it's five million, they're a problem. (Depending on the size of country and military, I'm pulling numbers out my arse to exemplify a point, not as accurate measures).
Numbers matter. If you have enough people on your side and willing to join the throwing for your cocktails to make a difference, that might work for you. But if most of the populace are scared to lose more than they stand to gain, you'll end up with the brave throwers arrested or killed, the media denouncing their "undemocratic" acts and possibly the people even more afraid to do anything.
Any revolutionary movement will need to hit a point of critical mass that allows it to succeed. It's hard to gauge just when that point is reached, but if you misjudge, you'll end up another failed insurrection.
