Black Light From a Smart Phone

Have you ever wanted a black light to see stuff? But didn't want to pay an arm and a leg for one? Well I have good news then, but you probably already know because you clicked on this add. So if you just somehow randomly ended up on this page and didnt read the title, were going to make a black light using nothing besides 1)any smartphone, sharpies(markers), and scotch tape! I hope you like it as it is my first Instructable, and if you do please vote for me in the Phone Contest! Thanks!

What you need;

1) A smartphone, any one will do for this as long as it has a flash light on it. I'm using an Iphone 6.

2) Scotch tape, I guess any clear tape will work though.

3) Either black and purple sharpies or markers. I'm using a blue sharpie and a purple marker.

Put the first piece of tape over the light on your phone and color it BLUE. Tip; make sure there is noting under the tape and the tape is flat against the phone.

Do the same thing you did with the blue tape, but this time with purple for the next TWO pieces of tape.

Now you have a blacklight made out of a few things and your phone you can make in just a few minutes! Plus you can carry it around in your pocket and whenever you want a normal light again, just take the tape off!
