Let’s Begin…

Your friend’s birthday is tomorrow, and he’s turning… well… you’ve forgotten. A ginormous cake has been prepared and your job is to sculpt his age as the chocolate centerpiece. The birthday boy is a giant, and you’re afraid that if your forgetfulness becomes known, you’ll become part of the feast. Can you figure out your friend’s age before the party? Marie Brodsky shows how.

Suppose there are 5 candles. What on/off starting pattern would make it easiest to figure this out (i.e. require the least effort from you)?
