神奇的塑膠瓶3D全息投影機 | DIY簡易全息投影儀

In this video, we show how to build a simple yet stunning 3D hologram projector using a clear plastic bottle and a piece of PVC film. The device works on the principle of Pepper's Ghost, creating floating holographic images that can be displayed by placing a phone screen in front of the projector. The tutorial covers selecting a suitable bottle, cutting and positioning the PVC film at a 45‑degree angle, and assembling the projector in under five minutes. The project is not only a fun science experiment but also a potential home‑based business, as the maker can produce professional versions and sell them on platforms such as Etsy, eBay, and Amazon Handmade.
