How To Block All Cell Phone Reception During Classes

Smartphones have become the latest and greatest accessory for high school and college students. They have also become the latest and greatest nuisance in the classroom. Students are constantly using their phones to text, sext, and generally not pay attention to the lessons being taught. What is a teacher to do?

Simple. Install a hideous piece of artwork in your classroom and watch the magic happen. Will students become so mesmerized by the art that they’ll put away their phones and contemplate their existence? Will they become enraptured by the high-quality print that they throw away their phones for good?

Heck no! The ugly painting has a cell phone jamming machine hidden inside! According to the manufacturer, Chinavision, this painting “covertly and completely blocks mobile phone signals in an 80 meter radius.” This ridiculous piece of ‘art’ actually has a tell-tale cord coming out its side, a remote, and even numerous USB and other ports. Not something you see in your typical piece of art. Fear not, as Chinavision states this painting is ‘inconspicuous’ and perfect for many settings:

The inconspicuous painting design effortlessly blends in with (and easily mounts on) the wall and is ideal for churches, hospitals, libraries, museums, movie theaters, class rooms, and for business meetings and legal proceedings.

We’re guessing the in-class conversations will happen like this after the ‘painting’ is first installed:

  • Johnny: Wow that’s some awesome art! Not as awesome as YouTube though. Hey Susie, check out this funny cat video, it’s way cooler than what Prof. Smith is talking about!
  • Susie: Let’s see it then! This sure is taking a long time to load Johnny…
  • Johnny: Yea, what gives? Maybe I should restart my phone.


  • Johnny: Now I don’t have any bars! What the @#$%? I can’t really get up to head to the window…I guess I’ll listen to this lecture about the history of EduDemic. Susie? Susie?! Wake up!

And so forth. While this device will likely never make it to the classroom, it is amusing to think that it might. Since most students say they keep their cellphones with them in class just in case of emergency, it would likely cause quite a ruckus if students found out a school was jamming cell phones. Still, it doesn’t hurt to dream…

    I think my local Home Depot has this art installed somewhere. That, or else they've encased the store in lead or something.

      ha! i believe it. a lot of those big box stores have issues getting adequate cell phone signals. I've lost signal on AT&T at nearly every Target I've ever been in.

    The same as we did when we were at school! Use a landline for emergency calls only.
