While cleaning out my office, I found one of the first Bio\-Wafer in an old bag. Although it was completely broken and about 8 years old, the vibration is still like the first day. Why this is so, I explain in this short video.
Unfortunately, the video does not have a particularly good picture quality, as it was spontaneously recorded with an old cell phone in low light. However, the message is of high quality, because it shows that the bio-wafers still function reliably even after years and violent shocks - as soon as they start oscillating again.
