a great treat arrived in the mail today...marg sent us a book called 'the ultimate book of kid concoctions' and it truly seems to be as described...a great selection of recipes for paints, glues, clays, putties, and yes, muck. the girl and i chose the *muck* for an activity during edgar's naptime.
3/4 C corn starch
1/3 C water
mix it up, let it sit for a few minutes, then have fun!
this stuff is liquid until you squeeze it, and then it firms up very convincingly only to melt away as soon as you relax your grip...very good fun.
