It’s been more than 35 years since Dr. Peter Venkman (Bill Murray) got slimed from head to toe in 1984’s Ghostbusters, and the oozy ectoplasm is still as popular as ever. With Halloween around the corner, why not make you own slime to add that extra touch to your costume or decor. The good news is creating your own slime is pretty easy. All you need is water, liquid starch, white school glue, and food coloring. Mix together 1/2 cup water, 1/2 liquid starch and 1 cup water in a bowl. Once it starts to come together, add the food coloring for the color you are wanting. Although this slime is non-toxic, it isn't mean to be eaten.
