{"product_id":"klein-bottle","title":"Hand-Blown Glass Klein Bottle","description":"\u003cp\u003eThis Hand-Blown Glass Klein Bottle is a mind-bending mathematical marvel. A Klein bottle is a surface with no inside, no outside, and no edge, where the neck passes through its own body and connects back to the base. It is a famous concept in topology that challenges our everyday sense of space. Crafted in clear glass, this model turns that abstract idea into a beautiful, tangible object you can hold and admire.\u003c\/p\u003e\u003cp\u003eThree size options are available, from a compact version for a desk or bookshelf to a larger piece that stands out as a true centerpiece. The flowing curves and transparent glass catch light beautifully, creating reflections that shift as you move around it. It looks elegant in offices, studies, libraries, and classrooms, and it inevitably sparks conversations about math, geometry, and the strange shapes that exist beyond three dimensions.\u003c\/p\u003e\u003cp\u003eThis Klein bottle makes a unique gift for mathematicians, physicists, engineers, teachers, and curious minds who love puzzles and paradoxes. It is perfect for graduations, retirements, birthdays, and academic achievements. Because it is hand-blown glass, handle it with great care and display it on a stable surface away from table edges. Clean it gently, and keep it out of reach of children and pets.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Hand-blown glass Klein bottle\u003c\/li\u003e\n\u003cli\u003eConcept: One-sided topological surface\u003c\/li\u003e\n\u003cli\u003eSizes: 3 size options\u003c\/li\u003e\n\u003cli\u003eUse: Desk, shelf, classroom, or office display\u003c\/li\u003e\n\u003cli\u003eCare: Handle with care; decorative use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Science Decor","offers":[{"title":"Small","offer_id":45857536442503,"sku":"45313578-s-size-5-4cm","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Medium","offer_id":45857536475271,"sku":"45313578-m-size-10cm","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Big","offer_id":45857536508039,"sku":"45313578-l-size-16cm","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/3194\/0999\/files\/Klein-bottle-Science-Decor-1682461647.jpg?v=1789426513","url":"https:\/\/axiomgifts.com\/products\/klein-bottle","provider":"Axiom","version":"1.0","type":"link"}
