my particles are not showing up

i am trying to play my particle when my ball hits a brick. its a course from udemy i am doing right now but they want me to use unity 4.6. But i didn’t want it so i just used unity 5. when i play it does load the code because i printed it out. but it doesn’t show me the particles. it also changes color btw when i look at the particle.

May be particles are playing but you are in 2d mode so i suggest just off your 2d mode and press CTRL + F to focus the maincamera to particles.
