Bubble Boy Bookends - Weasley Harry Potter

"Bubble Boy" is a magical item mentioned in the Harry Potter series, specifically in the books. However, its mention is very brief and is only found in the additional details provided by writer J.K. Rowling on Pottermore, a website dedicated to the Harry Potter universe.

The "Bubble Boy" is a magical bookend created by Fred and George Weasley, who are renowned for their eccentric designs. This bookend can be placed among the pages of a book and create a kind of "bubble" around the reader to protect him from unwanted observation while reading. This item represents an example of the humor and creativity of the Weasleys twins. However, it's not mentioned in the main books of the Harry Potter series and can be considered part of the additional details of the setting provided by J.R. Rowling.
