These are cute and would be really great, except I couldn鈥檛 get them to stick. You have to melt the glue with water, but then make sure it鈥檚 not wet while it鈥檚 sticky, dry your teeth and stick the fangs to them. You have to do this in under 5 seconds because the glue cools down so fast that by the time you get the glue dried off and your teeth dried, the glue has hardened and is no longer sticky.
