Like a Möbius strip, if you trace a path along its surface, you will travel on both sides of the surface before returning to the starting point.\u003c\/p\u003e\n\u003cp\u003eIn the mathematical field of topology, it is a 3D immersion of a closed, one-sided, non-orientable, boundary-free manifold. A true Klein Bottle does not intersect itself, so it can only fully exist in 4 dimensions.\u003c\/p\u003e\n\u003cp\u003eBut in the same way a 2D shadow is cast by a 3D object, this can be considered the 3D “shadow” of a 4D Klein Bottle—the closest we can get in our universe.\u003c\/p\u003e\n\u003cp\u003eA perfect gift for a math or science enthusiast.   Height: 11 cm (4.3\")\u003c\/p\u003e","brand":"AliExpress","offers":[{"title":"Default Title","offer_id":41601029406854,"sku":null,"price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1785\/9395\/files\/11AEA16C-F47A-4FB6-B76A-C9DF01921D16.jpg?v=1746555235","url":"https:\/\/becausesciencedc.com\/products\/klein-bottles","provider":"Because Science","version":"1.0","type":"link"}
