Press up arrow to start. The fireworks go where you go so move your mouse pointer around a bit so they go somewhere else as well. Have fun!
I got some inspiration from a book I read when I was younger. I wanted to make something colorful and when I looked in the book there was a list of ideas of fun coding ideas. I thought a Simulation would be fun. The other things are by me (I didn't use any code from any book), I don't know anybody else with a similar project so I don't know if I need to credit someone so it could be that code is similar. I believe in fairness so I wouldn't copy or use anybody else ideas or code without asking and giving them proper credit.
