lasers
Seeing as all 3 primary colors of laser pointers are now available.
what would happen if i had a red, blue and green pointer and crossed all the beams?
would the spot in the middle be white.
similarly if i crossed blue and red would i get magenta,
similarly if i crossed blue and green would i get yellow
similarly if i crossed red and green would i get cyan
???
if so would nt it be possibel to get any colour laser light by mixing combimnations of these as one beam?

Yes, if the colours were pure you would get white.
Your other combinations aren't quite right:
Red and blue give magenta (the complement of green).
Blue and green give cyan (the complement of red).
Red and green give yellow (the complement of blue).
In various proportions you could get any colour you like. This is additive mixing as used in colour television -where you actually mix generated light.
Most colour we see is from paints, dyes and pigments where your three "artist's primaries" are cyan, magenta and yellow -the three inks in your computer printer - from which you can get any colour.
