Dear Ken,
Glad to hear that you found something that suits you, even if it takes
modification.
As for killing the grass, practically any thick but non-toxic liqud
will kill grass if not hosed off.
Slime itself is edible.
The page that I used to link to on the Slime site has vanished, but
your ice cream probably contains Slime's chief ingredient, propylene
glycol:
