It's Not Easy to Be a Man After Travelling to the Future

In the next room, the group pulls out all of the new items that have been designed for the group. The first item is a "musical infant bed" that will automatically select the appropriate tune for the infant based on the brain waves of the child's brain. The second item is "a fully covered transparency" that can change between half- and full-transparent modes. The third item is an "auto-regenerative tube" that the body can use to increase its own growth. The fourth item is the "books of treasure" that are available on the web. The narrator tells the group that the books are useless because they are written by people who have no idea how to earn money. He tells them that they need to go to the web and find out if there are books that are still in print that they could use to make some money.
