Stan Melby led an activity to make snot using glue, borax, hot water, food coloring, and other materials. The activity involved mixing glue and water in a red cup, adding borax and food coloring to hot water, and then stirring the colored mixture into the glue mixture. Participants then used their hands in a dishpan to work the mixtures together to create stretchy snot, being careful not to eat the non-edible snot.
