"The Star Lookout" puts a telescope, sleeping bag and electric s'mores station on a Rivian R2.

How Big Is a Shooting Star?
Next story: Mark Rober's Jenga fix involves a wrist-mounted air cannon
A shooting star can begin with something smaller than a grain of sand. Mark Rober uses that surprisingly tiny starting point for a much larger build in "How Big Is a Shooting Star?", his only new upload this week.
Working with Rivian CEO RJ, Rober turns Emery's winning viewer drawing, "The Star Lookout," into a desert stargazing perch. A geodesic dome sits on the R2's roof, with a panoramic view of the sky, a telescope and somewhere to curl up. The electric s'mores station takes care of the terrestrial refreshments. The clip also showcases Rivian's vehicle as part of their joint design project.
The Short has reached roughly 680,000 views. In the comments, the small size of the particles behind shooting stars supplies one point of surprise; the telescope attracts questions of its own. Another viewer imagines taking the vehicle concept further with a miniature CrunchLabs inside.
Rober added 600,000 subscribers over the week, while his daily views sit slightly below their usual level. Across the science channels here, his weekly view gain is the largest, with Vsauce also adding subscribers and AsapSCIENCE enjoying an above-usual daily viewing pace.
For Rober, the busiest video right now is "The Insane Science Hidden in These Toys," followed by "I Solved Every Board Game." That statistics-fueled outing credits U.S. National Monopoly Champion Richard J. Marinaccio for research help. And the older "I Discovered a Lost Plane" continues drawing substantial attention, months after its release.

@c1ph3rytSee it on YouTubeI’d put a mini version of Crunch Labs in the car, accessible via a staircase inside the vehicle—or maybe a "MarkMobile."
