Rottbott's method should work fine.
How are you generating the random vectors?
My guess is that you are using Rnd(1.0) whereas to get the tri's to move in any direction you should use Rnd(-1.0,1.0)
For a more perfect? explosion just calculate each triangles normal from its 3 verts to get the direction vector you need the tri to move.
