"Dr Anton Rayner passed on to me, as Custodian of the famous Pitch-Drop Experiment at The University of Queensland, your request to use some of the material on our website. I see no problem with that. I would simply ask that the acknowledgment should read "The University of Queensland - Physics".

Thank you for your interest in this experiment.

[edit] Fair use for Pitch drop experiment

  1. Its inclusion in the article adds significantly to the article because it shows the subject of this article and how the event depicted was very historically significant to the experiement.
  2. A replacement image at the same drop position cannot be created until some time between 2008 and 2012 based on previous drop occurances.
  3. To replace with this image with one taken at the same time period of the experiement could not be produced for 70 years.
    Conditions 2,3 make the assumption that a photographer will have access, take and provide a free license image. Gnangarra 14:11, 16 December 2006 (UTC)
