Weasleys' Bubble Boy and Puking Pastilles bookends collection

"Bubble Boy" and "Puking Pastilles" are two of the products created by the "Weasleys' Wizard Wheezes", the firm established by Fred and George Weasley in the Harry Potter books.

"Bubble Boy": we are talking about a magic bookend that I've mentioned in the previous answer. The "Bubble Boy" is designed to protect the reader from inquisitive eyes, creating a sort of bubble or barrier around the reader, thus allowing them to read privately.

"Puking Pastilles": The "Puking Pastilles" are candy that induces the throw-up. These treats are one of the most renowned and popular products sold at the Weasley's Wizard Wheezes. When eaten, they cause sudden nausea and throw-up. They are often used for pranks and mockery of others.

Both of these products are examples of the Weasley twins' humor and creativity and their eccentric inventions within the Harry Potter wizarding world.
