Gigantic Klein botttle

This may be the largest Klein bottle (lovely multilingual dissonance there!) ever made. Klein bottles are basically Moebius strips with one extra dimension — bottles that have one continous volume without any "inside" or "outside." This Klein bottle was made by Cliff Stoll (who wrote the classic true-cybercrime thriller The Cuckoo's Egg) who runs the Acme Klein studio in the East Bay. I've bought one of Cliff's Klein bottles as a gift for my mathematician father, and it was very appreciated.

Acme made this 1.1 meter tall, 50 cm diameter, 15 Kg clear Pyrex Klein bottle in conjunction with Toronto's Kingbridge Centre and Killdee Scientific Glass.
