Gallery of Fluid Motion Submission Process:

1. Authors must agree to make their entry available to the public under the Creative Commons Attribution-NonCommercial 4.0 International License. Submitters will be asked to grant the American Physical Society a non-exclusive right to redistribute and reuse the content, which may include commercial uses, posting the video on the APS YouTube channel, displaying the video at other events promoting physics and art gallery installations. In addition, APS will need permission to make your video available to media outlets who would like to provide press coverage for the Gallery of Fluid Motion and/or your video.
   Please note that you will retain copyright to the work, and therefore you may reuse your content without seeking further permission, including within future publications.
2. Poster and video entries must not duplicate one another. Each group should submit either a poster or a video presentation (not both) on the same topic.
3. All submissions (poster and video) must be completed and uploaded to the Gallery before 5:00 p.m. ET on Thursday, Sept. 17, 2026.
4. Main submitters must be members of APS and be able to log in to their accounts.
5. For poster entries, it is recommended that posters be sized 24" × 36" or 36" × 24". It is expected that the submission includes photographs and/or graphics, accompanied by concise explanatory text with no formulas, as well as the names and affiliations of all authors.
   The Gallery of Fluid Motion is not a venue for technical posters, and the poster should not include formulas. Scientific posters can be submitted for consideration to the DFD Annual Meeting by July 24, 2026.
6. For video entries, the video must use the MP4 format (1920 x 1080 resolution recommended, using common codecs), but must meet the following guidelines:
   • Maximum length of 3:00 minutes. Longer entries will be truncated abruptly at the maximum length.
   • The video must use a black title screen with white text stating the video title, contributor names, and affiliations. Do not include the entry number assigned by the submission system. See example title slide below.
   • Audio can be included as part of the video. Please note: copyrighted music or other audio must be properly licensed so that the video can be made available under the Creative Commons Attribution-NonCommercial 4.0 International License and hosted on third-party services such as YouTube, Vimeo, etc.
7. Authors are allowed to submit multiple entries, as long as they cover different topics.
8. All completed submissions will be assigned a permanently citable DOI record that can be used to reference the work.
