Payphones are uncommon as of late, so its mere existence ought to garner some consideration. Anybody who appears to be like on the payphone will then discover a message imploring them to dial 7836 for “STEM.” In the event that they accomplish that, the payphone will pop open to disclose the library inside. That’s, after all, full of books that may assist individuals broaden their data on science, know-how, engineering, and math. It provides a enjoyable, interactive layer to the usual Little Free Library, whereas additionally demonstrating what an individual can obtain with the data inside.

Shrivastava began this venture with an actual payphone that got here from a laundromat. He then cracked that open to entry the electronics inside and a rating of $3.25 in free change.
