I HATE spending my "point" thingies on actually ASKING questions, but I'm far too lazy to look this one up.
Just what is the difference between regular chalk, and that "magic" ant chalk? I know for a fact that the "magic" chalk will not only deter, but also KILL ants. Is this also true with regular, writing on the chalkboard, drawing crappy pictures on the sidewalk chalk?
Please cite your sources. Thanks.
