Does Salt make ice melt faster?



 We used table salt, course salt and ice cream salt.
We were wanting to see which one would melt the
ice faster.  I could not really tell.  I guess if we had
three pieces of ice and tried each one , 
it would have been easier to tell. 
 Once the ice started to melt and crack.
I put food coloring on it so they could see the color 
go into the ice.  We took turns using a screwdriver
to chip away at the ice.  They had a blast!!
