Using Evian Spray?

A few days ago, my friend just got herself into this makeup addiction after watching Youtube videos.  She started telling me these random things.  One of them was concerning my Evian water spray and my MAC 187.  She told me that if I sprayed a little of Evian water on my MAC 187 bristles prior to applying foundation, the brush will not absorb all my makeup product and it'll be easier to clean afterwards.  I've tried it and it works! =) So it's definitely an interesting fact that I never knew.  So if you never knew either, try it out!
