First Meal in Japan

So, we flew in late. We got to our hotel, and decided we could NOT be bothered going out to find something to eat. The vending machine in the hall had "hot meals in 8 minutes". Basically, after putting the ingredients in the correct spot, you pull the string. A chemical reaction begins inside and cooks your dinner. At one point, I felt like I was holding a bomb and might need to throw it out the window before bringing the building down.
