1:14 Science Behind it

I have here is a Standard red laser 5MW, Green laser 5MW looks more brighter than the red and that’s because our eyes are 35% more sensitive to green light. The third laser is violet 5MW. I got mine on Amazon for around $15 US for all 3 lasers.
I bought the Glow in the Dark paint at the local craft store. 

So I painted the glow in the dark paint on a piece of paper. I used a couple coats.

The glow-in-the-dark paint is made up of special molecules called phosphors. To move to a higher energy level, they need energy from photons. When photons from a light source hit the molecules, they excite the electrons. 

The energy of a photon is based on its wavelength. If you think of a rainbow, red has the least energy and violet has the most energy. 

Due to the wave particles of light. You have to have a wave length of light that is shorter, than the wave length light that the glow in the dark is admitting. So that is why Blue/violet works so well. 

The amount of how much each color works is like a rainbow with Red,  being the least amount and violet being the most.

So glow in the dark paint is fluorescent and what that means  is absorbing the light from the lasers and slowly releasing light.
