If you think getting past a reviewer in something PNAS is hard, I got one for you that might be harder! Frontiers for Young Minds, where the reviewer can be a literal 10 years old.
If you're a science educator, I highly recommend checking out this journal. A lot of eye-level, high-quality texts, written by scientists, reviewed by kids.
