Tom, your comment on adapting effects made me realize that Dean Dill's "Explosion" is the multiplying bottles done with coins. Not really relevant here, I'm just sayin'.
Curtis, in addition to the fine advice above, here's what I saw:
-At the end, you're shooting for a clear display of a tableful of bottles, so make sure the tubes aren't blocking anyone's view of that. You've also got a large table, so to create the impression of fullness, you've got to spread the bottles out, or use a smaller table.
-Here's a new effect idea I've been playing with: suppose you're introducing a new drinking game called "Shot in the dark". You've got three tubes, and one of them has the glass in it. If they find the glass, they win a drink. As you move the covered glass around, it's clear that it makes noise, so you put bottles in the other two tubes to compensate. The rest is obvious, but this presentation allows you an extra set of gaffs, making the end display that much bigger.
-The most important part of your communication with the audience is any part where they do something at your request. If you ask them to all yell something, and it's clear from the effect, and your manner, that it really doesn't matter what they do, then they'll get the feeling that you're wasting their time and effort. Even if the request is intended to be a toungue-in-cheek gag, you should respond to their response. They're doing something for you, it's rude to ignore it.
All in all, good first outing.
