how long does it normally take for them to shut themselves off?
You ask one of the tribesmen this question. What would the other tribesman say if I aked if that was the right road to the Hilton. The correct road will be the opposite of the one that the tribesman says. If you are asking the tribesman who tells the truth all of the time, he knows that the liar will say that his road is safe, therefore the tribes men will say its safe. hence you choose the other road. If you are asking the tribesman who always lies, he will know that the tribesmen who tells the truth will say yes tha his road is the safe, so he lies to you and says NO therefore the other road is correct. True that you have no idea which tribesman you are speaking to when you ask the questions. That's the whole idea, this question will get the correct answer out of either the liar or the truth sayer.

Depends on type of resin and application. Different resin bases are made from different sources thereby having unique requirements for extraction and modifying. The type, use and composition of the resin will also determine cure time. There are resins that cure in 12 hours and others that cure in more than 12 months (one used by the Egyptians from fish oil for the composite bows). Look up the various types and what they are made of, applications and cure times and then explore the types you are interested in.
