An antique doorbell?

Wow! Fascinating and stunning. I have long practiced visualization techniques to stay healthy - imagining T-cells and B-cells and macrophages devouring and attacking any cancer cells in my body. Now I now what they actually look like.

Wow! You guys are rough. I was just trying to find some interesting stuff to post. Next time, I'll check Snopes first - probably should have thought of that before. Guess I'm just not as much of an expert on physics and video production as the rest of you. But at least it generated an interesting discussion. Thanks for all your comments and explanations.

I watched this video perhaps a dozen times, trying to see any sign that it is fake. I'd love to hear details from those that think it s fake - please tell me what you see!

Wow! I had no idea there were GIFTS involved. Thanks! It was fun.

I can't believe it - I actually guessed this. I have a truly demented mind.
