Inventor Sergeii Gordieiev, best known as “The Q” on YouTube, has built a custom split-wheel bike that actually works. More specifically, it has two half-wheels rather than a single back wheel. How so? First, he needed to trim a couple of rear wheels in half, while still keeping the hubs. Next, tire sections were cut to match.
Alaina Gassler, a 14-year-old from West Grove, Pennsylvania, took home $25,000 in this year’s Broadcom MASTERS STEM competition for her simple, yet clever, solution for removing blind spots in vehicles. It’s officially called “Alaina’s blind-spot annihilator,” and it consists of a webcam mounted outside the passenger side of the car, which is used to record the areas that drivers can’t see in their mirrors. A projector then shows the live video on an A-pillar on the passenger side.
