Amazing, startling, FAST- and incredibly easy to do!
You won't be disappointed with this one!
 

Show two clear glasses, one with beads of all one color and the other with all beads of a second color.
Mix the beads together into one container, and shake them to really mix them up.
Place both containers behind your back, and instantly bring them in front of you again- the beads are separated by color!

This easy trick practically works itself, and can be seen well from a distance!

Comes complete.
