Polycarbonate bottles are a special plastic used to make bulletproof glass and water bottles, i.e Nalgene bottles at EMS. Polycarbonate bottles are dubbed "indestructable" and can withstand heats up to 523 degrees Kelvin according to www.ems.com. I was wondering, has anyone attempted to break one? If one was able to break the bottle, how did you do so? besides running it over with a car.

THIS QUESTION COULD BE BASED ON PERMUTATION OR COMBINATION. Suppose you knew a message had been coded using a Substitution cipher. If it took you one second to try out each key, how many days would it take for you to try all possible keys on this message? Definition of SUBSTITUTION CIPHER from WIKIPEDIA:In cryptography, a substitution cipher is a method of encryption by which units of plaintext are substituted with ciphertext according to a regular system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing an inverse substitution.
