Klein Bottle Kleinsche Fläche Never Full of Water, Glass Vase of Mathematical Geometry, Four-Dimensional Space Science Model decoration

Lovely little example of scientific glass blowing, great illusionary gift that will always stir conversation!

Interesting conversation piece if mathematics interests you.

Bought us a retirement gift for a maths teacher. Everybody was fascinated by this and loved it. However, it is incredibly tiny. I was expecting something a bit bigger.

Join is botched meaning it co.oletely loses the point of an infinity surface and you can't even fill it.

Does exactly what it says on the tin.

really good gag gift for my maths teacher

Product is about the best as you could expect for 20 pounds on amazon! I was pleased to see the bottle i received looked better than the design in the picture. Small scrathes here and there but nothing that takes away from the aesthetic.

Well this was a bit of a disappointment as I was keen to get this and show the kids how it works but it’s poor quality and only really good as a display piece. It’s got a lot of blemishes and marks on the glass and it’s quite fragile. It did however arrive in tact thanks to being packaged well. Unfortunately this bottle doesn’t come with a base even though the description says “with base” so keep that in mind. It is a nice design and style but just doesn’t quite hit the excellent mark. I’d say the value for money is poor so I probably wouldn’t recommend it but it does make a nice display piece of home decor in my kitchen.
