Is there a word for saying that I have found another different interest unexpectedly? Suppose that I was interested in say, Biology yesterday but today when I dabbled in Chemistry it also caught my interest (: made me interested) and therefore I got interested in Chemistry unexpectedly. Is there an expression for that?
In my own research I found stumble on Chemistry but most dictionaries say that that is more of discovering something than becoming interested in something (Merriam Webster).
Is there any expression for what I am intending to say?
