You show a small bottle of drink which can be examined. You unscrew the cap from the bottle and take a sip. You then push the cap into the bottom of the bottle where it vanishes and reappears back on top of the bottle, actually screwed back on. Can be immediately handed out again for examination. 

Part of the gimmick is based on an idea by Johnny Thompson and Dr Carlo.
