For example, the principle of refraction of light, the principle of air friction, the principle of vacuum propagation of light, the principle of uneven heating generating power, and so on. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Y3ZZ786 | | Are Batteries Required | No | | Best Sellers Rank | #669,888 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #4,574 in Decorative Hanging Ornaments | | Brand Name | DORAMI | | Color | Transparent | | Customer Reviews | 4.4 4.4 out of 5 stars (159) | | Included Components | Cord And String | | Is Customizable? | No | | Item Dimensions | 4.2 x 4.5 x 9.9 inches | | Item Dimensions D x W x H | 3"D x 3.9"W x 9"H | | Item Weight | 180 Grams | | League Name | Italian Soccer | | Manufacturer | DORAMI | | Material Type | Glass | | Mounting Type | Hanging | | Number of Pieces | 1 | | Occasion | Birthday | | Package Quantity | 1 | | Product Style | Modern | | Scent Name | Unscented | | Target Audience | Adult | | Theme | science_fiction | | UPC | 602463522107 | | Unit Count | 1.0 Count | ## Images ![DORAMI Transparent Solar Power Crookes Radiometer Metal Frame Sun Light Energy Spinning Vanes Glass Windmill Gift Home Desk Decoration - Image 1](https://m.media-amazon.com/images/I/61FIIfRPl1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Looks good, works well *by P***N on August 20, 2025* Looks good, well made and spun surprisingly fast in the window. ### ⭐⭐⭐⭐⭐ Something different *by A***R on January 19, 2021* It was fun to see it turning faster and faster when it got in direct sunlight!
