The Wolfbox MF100 battery-powered air duster produces a stream of air more powerful than a can of pressurized air. I've been using it to blow debris out of keyboards, dust from windowsills, cobwebs out of corners, and dirt lodged in cracks in my backyard wooden stairs. I wear ear protection when using it on the highest setting. It comes with four nozzle attachments and a USB-C charging cable. — MF

Finding a reliable local guide in a far away destination is not easy, but made a bit easier with GetYourGuide.com. This is a clearinghouse for local ebike tours, street food tours, museum tours, and city walking tours around the world. GetYourGuide does not run any of the tours; these are all staffed and run by local entrepreneurs so the quality will vary. But this site and app make hyper local guides easy to find, easy to schedule, and easy to pay. In my own experience, they are reliable and deliver what they promise. — KK

Whether or not you like the music of U2, you should watch the video memoir of its lead singer Bono. The format of Bono: Stories of Surrender, streaming on Apple+, is peculiar. Like an autobiography, this is an auto-documentary, a documentary made by Bono about himself. It begins with spoken-word monologues by Bono, mixes in music, dips in and out of him telling his Irish family story on stage, personal confessions of his own journey, punctuated by lyrics of well-known songs to fill out his biography. It is a performance, but also a record, an oral history. It’s a film version of his mammoth book autobiography, Surrender, but I appreciated this cinematic novella for its innovative approach to a memoir. — KK

This website generates random adjective–noun combinations and then pulls up corresponding Wikipedia and Google results. Some exist as entries, while others don’t because they’re too nonsensical. Either way, it feeds my curiosity and sparks new creativity. — CD

Richard Sharpe Shaver (1907–1975) was a pulp science fiction writer, best known for his articles that ran in Amazing Stories in the 1940s about an evil race of humanoids living beneath the Earth’s surface. Shaver insisted the stories were non-fiction. Later in life, Shaver came to realize that the patterns in rocks were messages written by intelligent beings of antiquity, and he devoted the remainder of his life to sharing his discovery with his small cadre of admirers. Richard Sharpe Shaver: Some Stones Are Ancient Books is a book of Shaver’s “rokfogos” research, complete with photos and typewritten rock-book translations. It was published by a delightful small press called The Further Reading Library. — MF
