I hate to be the bearer of bad news but that video was faked.
Here's the full explanation: https://twitter.com/MarkRober/status/1075767629703372800
He also initially claimed the package was placed in Illinois, but he edited the video after people called him out on it.
And he presents the device as something he engineered himself, only briefly mentioning that someone helped him. Another video shows that the other guy, Sean Hodgins, actually built it (find the link in jtokoph's comment below).
So who really knows? It wouldn’t be the first time something on the Internet was staged.
Its disappointing that Sean is getting absolutely zero credit. Mark Rober just keeps saying “I built”. There’s a link in the description but just suggests Sean has more build details.
He could have at least brought Sean into the original video for some credit. Who knows, maybe this was the deal and Mark is giving Sean all of the ad revenue in exchange for the views/subs/credit...shrug
He clearly mentions Sean and even includes a couple of frames in the video of Sean working on the device's PCB.

It sucks there was fake content in there, but the device was real and the fake actions removed.
Until I saw this subthread, I had no clue that he didn't design and build it. I don't recall any reference, even to a partner.
