YES - A Baby Klein Bottle!

A baby Klein bottle made by Cliff Stoll

Acme's Baby Klein Bottle

A mighty small Klein Bottle -- a German might say it's eine kleine Klein Bottle. (Or maybe, "eine kleine Kleinsche Flasche")

At 11 cm (4.5 inches) high, it's about the size of an avocado ... snuggles right into your palm. Ideal for elementary school topologists, as well as graduate students living under bridges or on street corners.

Includes all the features which have made our Classical Klein Bottle a hit: immersed (not embedded) in 3-dimensions with exactly one handle and one hole. Certified nonorientable, Y2K compliant, and made entirely from Baryonic materials.

While it rests upright on any table or granite optical bench, 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 a few thousand ergs of energy to set it upright.

This quality, shrink-resistant, zero-volume, borosilicate manifold is yours for a mere $46 ... less than it costs to own the Mayor of Chicago!

  • - Height about 110 to 120mm (4 to 4 1/2 inches)
  • - Diameter 55 mm (2 inches) give or take a smidgen
  • - Weight: 60 gm (2 oz)
  • - Displacement 140 ml (5 fluid ounces)
  • - Actual volume 0.0 ml (0 fluid ounces)
  • - Fully calibrated with a removable decal

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 Lands End to Penzance. Nor should you worry about it dissolving -- we have tested samples in water, acetone, methyl-ethyl-ketone, and Jello. Note that the fingers shown in the photo are mine (Cliff) and do not come with the Klein Bottles, although my fingerprints likely do.
