The Acme Klein Bottle (from Cliff Stoll and family)
Cliff Stoll (who is probably most famous for writing the wonderful Cuckoo’s Egg about tracking a hacker when doing so was almost recreational) runs a business making Klein bottles: Acme Klein Bottle. A Klein bottle is a weird shape (that doesn’t actually exist in three dimensions) with only one side. A bottle with no inside and outside. A bit like the Möbius strip has only one side.
John Graham-Cumming discusses Klein Bottles and Cliff’s business in a recent post.
Cliff has a whole page describing the properties of a Klein Bottle. It’s worth a read. Buying from Cliff is an experience in itself.
I haven’t described all that comes in the package, or what communication with Cliff via email is like. But if you want an experience that ends with a Klein bottle in your home, buy one.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
