China grass is an alternative to gelatin. It doesnt need refrigration for setting. We made these fun sensory bags for window or light table play. On the light table it also can be used for fun color mixing. Just boil 2cups water and add china grass till it dissolves. then add it to different containers and add few drops of food color. Let it cool for 10-15 mins, and its ready for play. This is totally tasteless and edible. So it is fit for younger children too. Now add the jelly into ziplock bags and seal the top with clear tape. We added some Q-tips for writing practice.
