Okay, this is really bugging me;
When SCP-2857 comes in contact with water it spontaneously reaches temperatures of under -500°C
You can't get colder than 0K, which if I recall is (around) -273°C. It's important to get the science correct when writing for the site and this is pretty simple stuff. Also, solid CO2 is a rediculously impractucal way to contain it- keeping it submerged in oil would stop any moisture, again basic science. Overall the anomaly isn't that interesting, but this stood out to me as a glaring error.
Try and get crit before posting a scip either in chat or on the forums, and if you don't get the science you're using, ask someone who does.
SCP-2258 can create an illusion in your mind of what it looks like. No one is positive about looks like but it is theorized that it has one independent form. It lives in the sea giving the facts that it can survive in any condition. SCP-2258 does not eat animals but plants such as seaweed and grass. SCP-2258 is not known to harm any living creature including humans, -24 and three staff votes.
SCP-2921 is a light-blue and dark-purple sphere approximately 5 feet by 5 feet by 5 feet. The ground around SCP-2921 is barren and unable to support plant-matter, and no wildlife will step within the 30 foot by 30 foot perfect circle surrounding SCP-2921. SCP-2921 is dormant and will remain dormant as long as no organic or man-made object steps within 15 feet of SCP-2921, -22 and three staff votes.
