You
can also tape down 2 oz portion cups inside
the Dixie cup in instead of sno cone cups. Don't limit yourself
to just water. Maybe add some orange juice or cranberry for
color?
You can also make chocolate shot glasses
this way as well. And why not make some rubbery jello
shot glasses? Just use less water so that they will
cure sturdy.
There
are directions for the chocolate shot glasses
here.
