You have two one-minute fuses. Unfortunately, they don’t burn evenly. All you know is that each one takes exactly one minute to burn completely. How can you measure 30 seconds?

    Is it possible to set on fire the fuse with both sides?

    Yeah. That’s what you need to do.

    Perhaps, another option is to split one of the fuses in half along its length?
