Acme's Medium Klein Bottle

A medium size Klein Bottle next to a billiard ball

A little Gem -- it fits in your pocket!

Ideal for the iternerant topologist, one sided time traveller, or the visiting postdoc without much room around the cubicle.

Includes all the features which have made our Classical Klein Bottle a hit: immersed (not embedded) in 3-dimensions, One handle, Y2K compliant, shrink-resistant borosilicate Glass. Certified one sided.

While it's stable on a table, we don't recommend this style for earthquake country, since it's easily tipped over. But because it's so small, it'll only take less than a Joule of energy to set it upright. No need to take weight lifting classes.

For optimal aerodynamic performance, our medium sized Klein Bottles have smooth curves. You can take advantage of this lustrous continuity to differentiate this manifold everywhere! Tested by simulated undergraduates and fully covered by Acme's Unconditional Guarantee.

Just $58 gets you a quality, rustproof, borosilicate zero-volume manifold ... a bargain compared to 6 years in graduate school!

Like ACME's other fine Klein Bottles, this is handcrafted from pure Borosilicate Glass ... Pyrex, Kimax, Bomex, or Simax. It has a bulk density: 2.23 gm/cm3 and expands just 0.000326% per degree C. This means that it'll shrink only a few microns when you trek from Tucson to Nome. Nor should you worry about it dissolving -- we've tested samples in water, acetone, methyl-ethyl-ketone, maple syrup, and jello.The billiard ball in the photo is help you judge the size, shape, and topological properties of the Klein Bottle;
