It takes 2 flicks of the switch and a portion of time you can't get back. Explanation:Christmas lights convert electricity into light and heat right? So, it doesn't matter which switches you turn on or in what order. Try one and wait 5-10 minutes. This should be enough time to warm up the light bulb if it is on. If it's not that one, the light will be off and cold right? Click the second switch. Wait another 5-10 minutes. Now go and check. If the light is on, great you know it's the second one. If it is off but hot, then you know the first switch was the one that worked. If it's off and cold (assuming it won't lose its "heat" in the time that's passed), then neither of the first two worked and the working switch must be the last, un-flicked, one.

Before the guessing starts each person picks a number from 0 to 19 making sure that no two people picked the same number, so each number from 0 to 19 gets picked by 1 person - for a given person let’s call this number “k”. Then each person assumes that the sum of all numbers in the envolopes (including their own) modulo 20 is equal to “k” - this then will uniquely define the number they will guess.
