ALLOWED

About

This subreddit is dedicated to showcasing interesting and entertaining chemical reactions. Read our Wiki for more information on the types of posts you will see here.. Due to our subreddit's size and variety of interesting gifs, over time this we have grown to be accommodating to other types of chemistry, physics and biology related gifs (those who would just like to view one type may use our filters on this sidebar).

Rules

1. Physical reactions are allowed, along with an extension of other gifs that we feel relevant to this subreddit which you can read about in our wiki here under the "Post Categories" section. Posts will be tagged accordingly based on what category they fall under.

2. Not every post that is not a chemical reaction is a physical reaction or relevant to this subreddit's accepted posts. For example a post featuring a can being smashed or the motion of a pendulum will be removed.

3. All link posts must be in either gif or html5 format. Any link post that is not in one of these formats will be deleted. Any interesting or relevant images or videos (whether they be about the subreddit or a demonstration) must be done in a self post.

4. No albums of gifs allowed in link post or self post form. This is due to trouble categorizing a post which often has multiple gifs that don't fall under one category and leads to a misleading post and confusion.

5. Reposts are allowed and will be tagged as such for filtering sake. They will not be removed unless a moderator deems the repost to be of a demonstration or particular gif that has been posted too often (e.g. Mercury(II) Thiocyanate Decomposition).

6. All link posts must have the source of the gif/html5 video posted in the comments. We expect the original poster to do this, however if someone else does so then it will not be removed. Reposts of a post with a source that do not contain the source in the comments will be deleted.

7. Link posts utilizing the gif/html5 format to skirt the rules will be removed. For example if a demonstration is posted that is a gif but is essentially static image then it will be removed. We will approach this rule on a case-by-case basis to avoid removing naturally slow/lengthy demonstrations to the best of our ability.

In rare cases, exceptions may be made by the moderators if a post is exceptionally intriguing and relevant to discussion in order to maintain quality standards.
