Question: what experiments can/will change the world

it’s kind of hard to know i think! sometimes people invent things like a new medicine (like vaccines) or a new bit of technology (like a mobile phone) and you can see how they’ll be used. other times it’s a bit more surprising – i don’t think the guy who invented the internet knew that it would turn out to be so important. i think the most important thing just now is trying to find a new way of making electricity without burning coal or oil, so that we can stop making so much pollution.
