    THE CLOSEST YOU’LL GET TO A 4D OBJECT IN OUR UNIVERSE

    A Klein Bottle is a 4-dimensional shape that has neither an inside nor outside.

    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.

    In 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. But 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.

    A perfect gift for a math or science enthusiast.

    Was disappointed in the size, but that's my fault! Still a cool item, just wish it was larger.

    The Klein bottle is a really cool gift. It was beautifully packaged and was shipped and arrived way sooner than it was supposed to. I am grateful to the shop owner for that because I told him it was a gift. The gift recipient was very, very pleased. Thank you so much!

    WE TAKE SCIENCE SERIOUSLY

    You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

    We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.

    With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

    Believe in yourself; for everything else, there's science.
