Aboard the Heart of Gold

1. Don't go on until you're actually holding the Gargle Blaster.
2. Have you tried drinking it or examining it?
3. Have you read the Guide entry on Pan-Galactic Gargle Blasters?
4. Read carefully what Zaphod says when he notices that his Gargle Blaster is missing.
5. There is absolutely no way that you can be holding a Gargle Blaster. The Nutrimat gives them only to Zaphod. You should never have developed this question.
