A few years ago, there was this hype about a new material called graphene. Graphene is basically graphite, but 2D and in a honeycomb shape. People had a bunch of crazy ideas about what we could make with it. People believed that we could almost immediately be able to create machines from sci-fi movies. But so far, we have made barely any progress. Some people are still overhyping graphene, while others think it is a massive disappointment. We have already create a few things with graphene and are getting ideas for more. Because these new ideas sound so promising, I think we should keep looking into graphene.
With graphene, we might be able to make something that can filter salt water. This could help many people who live in places with no fresh water close by. Because it might help so many people, it is worth looking into. Also, graphene can be made from waste materials like plastic and rubber. Plastic does not break down and rubber leaches hazardous chemicals into the environment when it breaks down, so this would be a great way to get rid of these harmful things into make something useful. These would be very useful inventions, so I believe that we should keep looking into graphene, even if it is a little pricey.
