Question: What was the first thing you discovered.....

That it takes approximately two months to grow zinnias during winter on your window, and that zinnias are growing better and look better than сosmos (flowers). Not a real discovery and certainly not the most exciting one, but that was my first ever serious science project at school. I think I was 13-14 then.
