There are wonderful scientific animations on the internet but it is many a times very hard to discern if they can be used anywhere you like without copyright infringements.

ISafeHQ (Internet-Safe Illustrations HQ) is a project that was started in October 2019. The aim of this project is to build a database of high quality (mainly physics) illustrations, animations, and demonstrations that educators/teachers/science-communicators can use for any purpose (class, lectures, talks, etc) for free under a Creative Commons Attribution 4.0 International License (click on the link to learn more about the license)
