Did you have them rip the white ones in half to demonstrate crack
rocks?

And it came to pass that Tara delivered the following message unto the

I remember doing something kind of like that in fifth grade, circa 1994/5
or so. The teacher also had demonstrated magma by making some sort of
"fudge" concoction (didn't have marshmallow creme, so it didn't really
"set up") which was later shared amongst the class.

<oldfart>Of course, even then it was still not considered "un-politically
correct" to give kids sweets, even in school. You know, since people then
weren't nearly as anal as they are about it now...</oldfart>
