Acme Klein Bottle

An Acme Klein bottle is a perfect gift for a mathematician, computer
scientist, or troglodyte. In Germany, it’s called a Kleinsche Flasche. A
Klein Bottle makes a great math gift and an ideal present for a
mathematician!

largest glass Klein bottle for the Kingbridge Centre!

Answer to my most commonly asked questions:

1) Yes, I am Cliff Stoll, and I make and sell Klein bottles. My
business is named Acme Klein Bottle.

2) Yes, I regularly send these to countries around the world.

3) Yes, you can safely order from this website, and I will send your
Klein bottle within 24 hours.

4) Yes, I pack each one very securely to survive the post; I
guarantee safe, speedy delivery.

5) If you are unhappy with your Klein bottle, I will refund your
money.

6) If this is a gift, I’ll print “Happy Birthday” (or whatever you
want) on the packing slip or the outside of the package. If you wish,
I’ll write your message on the bottle with a Sharpie pen.

7) No, I no longer do the hot glass work – I contract this out to
professional glassblowing shops. I do everything else myself – from
design to packing to writing the html on this website, with occasional
help from my son Danny, my daughter Zoe, and my wife Pat.

8) Yes, you are welcome to visit if you are traveling to Northern
California (San Francisco/Oakland/Berkeley) Call first – 510 654 3958
//but I’m really busy from mid November until Dec 31st//

9) No, I cannot engrave these glass Klein bottles. The borosilicate
glass laughs at laser beams and the compound curves defy X-Y tables..

10) Yes, there are many math jokes on this website, but despite that,
I really do sell Klein bottles

11) Yes, my son Danny and I designed each of these bottles ourselves.
Our designs are copyright © by Cliff Stoll

12) My website looks old-fashioned because it loads faster this way
and (mainly) I’m too lazy to rewrite it. I wrote much of it between
1996 to 1999 (before CSS was invented), I last updated this on Wednesday April 19th, after planting several daffodils in or garden).

13) Yes, that’s me in the [ video / book / talk / college / bowling
alley ]

Francisco, and epsilon away from some boundary)

ARE YOU A STUDENT, AGE 12 TO 17? Do you like the
kind of math humor that’s on this website? Then consider one of the
terrific summer math camps! Several that come to mind: the Hampshire
Summer Studies in Math (in Amherst, Massachusetts during July &
August… learn why the Yellow Pig endorses 17 varieties of Acme Klein
bottles — hcssim.org).
Also, the MathILy program at Bryn Mawr (five weeks of maximum
mathematical marvelousness) (www.mathily.org).
I’ve also heard great things about Epsilon Camp in Utah (well, one of the Epsilon
camp counselors visited, and she really impressed me!) There are
dozens more camps– see a list of these camps at www.ams.org/programs/students/emp-mathcamps …
feel free to ask me for opinions or comments about these various math
camps. Also — Math Circles are springing up around the world … find
out if there’s one in your neighborhood:
