La Quinta Columna (The Fifth Column) is a group that has researched and published extensively on nanotechnology in the forced injections and 5G. Here is a two minute video in which they present a simple experiment, utilizing a smart phone, to test for radio-signaling from nanotech devices within any of us who were deceived and coerced into the misrepresented and dangerous injections. If reliable, this may also be a simple tool to help discover which people who, though they were coerced into the injections, were fortunate to receive the placebo.
