Ramses Martinez never bothers turning on a TV when he checks into a hotel. The room's safe is a much more entertaining option. Martinez loves puzzles, and he considers lock-picking one of the ultimate tests. The @purdue.ie and @purduebme professor gave @purduecheme student Yasar Dambo the lowdown on his hobbies, including different kind of “enhancements” (hacking) Martinez does in his spare time, in the latest #PurdueEngineering "Office Hours" video series. The latest episode will drop Friday. #officehours #lockpicking #puzzles
