Science can be done for several reasons. Sometimes, you just want to know the answer to a question. Scientists do experiments because a lot of people want to know the answer to a question. The work they do could possibly impact many people, hopefully in a positive way.
For example, a company may want a chip bag that is biodegradable. A scientist will figure out how to make it. A bag that will decompose and not sit in a landfill is better for everyone on Earth.
Who would care about your experiment? Why?
