How Engineering Students in Pisa Built the World’s Largest Paper Airplane

By Bill Smith July 4, 2026

Inside a vast exhibition hall in Bologna, one student stepped onto a platform three meters above the floor and gave the aircraft a firm push. The wings extended farther than a city bus is long, yet the structure left the edge cleanly and settled into a steady glide. It traveled 59 meters before its nose met a line of columns at the far end of the space. That single launch secured the Guinness World Record for the largest paper airplane ever built and flown. Engineering students from the University of Pisa created the aircraft, known as ICARUS. It spans 20.04 meters from wingtip to wingtip, measures 7 meters in length, and weighs 28.49 kilograms at completion.

This Yellow Liquid Turns Into a Black Gel to Store Energy for Months

By Jackson Chung July 3, 2026

Northwestern University chemists have built a material that begins as an ordinary yellow liquid and rearranges itself into a black gel whenever it absorbs energy. The change locks electrons inside a new structure that can hold them for months when sealed away from air. Open the container later and oxygen triggers the release, powering chemical reactions even in complete darkness.

Apple’s Thinnest iPhone Air 2 Set to Return With the Camera Upgrade Everyone Noticed Was Missing

By Jackson Chung July 3, 2026

Apple launched the first iPhone Air last year as a deliberate step toward extreme thinness. At just 5.6 millimeters thick, the device used a titanium frame and careful internal engineering to deliver a phone that felt unlike anything else in the lineup. It sold well, roughly twice as strong as the model it replaced in some markets. Yet feedback quickly highlighted two areas where the bold design created clear compromises: a single rear camera and battery life that struggled to match expectations during long days of use.

How Sony Manufactured Those Black PlayStation CDs in 1997

By Bill Smith July 3, 2026

PlayStation Underground captured the scene at Sony Disc Manufacturing in Springfield, Oregon, just after 7 a.m. The night shift had already run for hours, and stacks of fresh discs waited for the next steps. Everyone asked the same question back then. How did those distinctive black PlayStation CDs actually get made?

Why Shokz OpenRun Pro 2 Delivers Better Sound and Rock-Solid Stability for Active Lifestyles

By Jackson Chung July 3, 2026

Runners and cyclists who train outdoors face a constant balancing act between enjoying their audio and staying safe amid traffic and other users on the path. Sealed earbuds can isolate a person too much from honks, voices, or approaching bikes. Traditional over-ear options add bulk and heat during intense efforts. Bone conduction, like on the Shokz OpenRun Pro 2, priced at $119.95 (was $199.95), sidesteps both issues by sending sound through vibrations in the cheekbones straight to the inner ear while leaving the ear canal free.
