Rear Vacuum. Aerodynamics.

Rear vacuum (a non-technical term, but very descriptive) is caused by the "hole" left in the air as the car passes through it. To visualize this, imagine a bus driving down a road. The blocky shape of the bus punches a big hole in the air, with the air rushing around the body, as mentioned above. At speeds above a crawl, the space directly behind the bus is "empty" or like a vacuum. This empty area is a result of the air molecules not being able to fill the hole as quickly as the bus can make it. The air molecules attempt to fill in to this area, but the bus is always one step ahead, and as a result, a continuous vacuum sucks in the opposite direction of the bus. This inability to fill the hole left by the bus is technically called Flow detachment.

[boxr_]

actually pretty funny how that thing is so incredibly aerodynamically inefficient that the box can’t fall out.

[cmoore]

So that’s how all my items end up destroyed but delivered

[MoliminousTheater]

Hey ups is getting better at handling packages.

[teriousrobinson]

This isn't aerodynamics, that's woody and buzz trying to find a comfort spot

[mark__whitfield]

I can tell you with certainty that my rear is not a vacuum

[thomaspayne]

I did this once with a refrigerator.
It stayed on the ground tho.

[yuyuy]

box: "finally I'm free!!"

physics: "not on my watch"

[D-Man_Jam]

Box: *falls*

Magic air that isn't there: _"Yo, I got you fam."_

[shayde]

Ups: *Your order has arrived*
Me: why tf is it damaged?
✨Science✨

[Stickmanic]

I’m so glad they explained the physics instead of “OOh MaJiC”

[RobReith]

That it happened twice in a row is pretty impressive.

[khalikovsaid]

That's how FEd ex delivers packages, no surprise they look like somebody lied on them, tbh

[Americanspy-hnkw]

Ah so that's what happened to my plates I ordered

[Rise_Of_The_Me]

Imagine falling out of the back of a I haul and just getting uno reversed

[Rake]

When the box falls out:

*"Ohh Hell naw"*

**gets back in**

[Chryztallic]

I feel like this is just a glitch in the matrix and will be fixed in the next patch.

[zanestathakis]

Hmm fast and furious physics don’t seem that crazy anymore

[Hobinator]

Lmao this is why my 4runner fills with exhaust smell with the rear glass open sometimes. Also explains how the headliner gets so filthy in back, it's road particulate matter getting sucked in.

[gwanerka]

I was on my boat the other day had an empty water bottle fly off the console and just dance on the gunwale for a good minute. Was too lazy to look up why that was. Love getting recommended shorts and other YouTube videos that are actually insightful.

[asianboiz]

I’m more impressed how it got back so neatly.
