Ideal for home or office décor, it requires no external power and serves as both a captivating kinetic sculpture and an educational physics tool, making it a perfect gift for curious minds and professionals alike. ## Description INTRODUCTION: The radiometer is educational and physical demonstration object that was invented by English physicist Crooks about 100 years ago. Today the Radiometer has become a home decoration or holiday gift.Of course, it can also be a physics teaching tool.HOW DOES IT WORK? The radiometer consists of a glass bulb with a partial vacuum.Inside are four vases which are mounted on a spindle.The vanes rotate when exposed to sunlight,artificial light or infrared radiation. Review: Great gift 12-13 year olds - Give your 12-13 year old something to think about... by challenging them with science, then turn the table by asking them why and how!! Great quality product very sensitive to light, works inside on a bright sunny day. Recommended.. Review: Very Impressive device! - This unit is very cool! It replaces a smaller one that has lived on our kitchen windowsill for well over 14 years, until my wife broke it one morning while opening the window curtains. Being much taller than the previous one, I’ve not yet found a safe place to place it where it might not be damaged. It is really nice, and I hope to find a safe place to mount it! ## Features - How it works - The glass Radiometer is made of a vacuum glass bulb. There is a rotating shaft and four blades inside. When it is exposed to sunlight, artificial light, or infrared radiation, its leaves will rotate. The stronger the light, the faster it rotates. - Exquisitely designed - Handmade from high-quality glass. Crystal clear, small and exquisite. It needs to be placed on a flat surface to prevent shattering. - The best decoration - It is suitable for occasions such as offices, living rooms, bedrooms, classrooms, study rooms, parties, etc. Place it on a desktop or windowsill, and as long as there is sufficient light, it can rotate continuously without requiring any other energy. - Creative Gift - Giving it as a gift to our family, friends, colleagues, and leaders is perfect. As long as there is light, it can rotate continuously, just like our emotions. As long as we treat them sincerely, friendship can be eternal. - Physics teaching tools - their formation can explain many physics principles. 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 | B07BGSMBX9 | | Age Range Description | Adult | | Best Sellers Rank | #111,872 in Toys & Games ( See Top 100 in Toys & Games ) #45 in Solar Power Kits | | Brand Name | DORAMI | | Customer Reviews | 4.5 out of 5 stars 102 Reviews | | Educational Objective | Physics Learning | | Is Assembly Required | No | | Item Dimensions | 3.54 x 3.54 x 8.66 inches | | Item Weight | 5.28 ounces | | Manufacturer | DORAMI | | Manufacturer Maximum Age (MONTHS) | 720.00 | | Manufacturer Minimum Age (MONTHS) | 180.00 | | Manufacturer Part Number | 645634546701 | | Material Type | Glass | | Model Number | 645634546701 | | Size | Large | | Subject | spherical | | UPC | 602463522039 | ## Images ![Large Transparent Solar Power Crookes Radiometer Sun Light Energy Spinning Vanes Windmill Gift Home - Image 1](https://m.media-amazon.com/images/I/51e4i958PEL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great gift 12-13 year olds *by J***A on January 6, 2025* Give your 12-13 year old something to think about... by challenging them with science, then turn the table by asking them why and how!!
