Although we expect humanoid robots or perfect machines at innovation fairs, the work presented there does not have to be so attractive. Sometimes, those innovations can be something tiny, but their meaning can be huge. Sometimes, we see things we have thought about several times, but someone else is persistent enough to push the idea to the end in the final product.
Lisa and Charles, together with their friends, are currently at the city's main tube station. You should attend one of the biggest innovation fairs. He's been waiting for this day for a whole year, but here's a problem. Someone has lost the bus tickets for the whole group. Lisa and Charles panicked and had to find the cards immediately.
They don't want this huge chance to fail because of some distraction and irresponsibility. Let's see what's going on at the intercity bus station and help our friends get to the place on time. And of course, let's wish them luck in successfully presenting the fair and returning from there with new ideas and knowledge that will lead them to new challenges.
