To make glow-in-the-dark glue, first acquire the necessary ingredients and tools including glow-in-the-dark chalk or dust, water, flour, salt and a hammer. Then, make a wheat glue by boiling a cup and a half of water and adding a half cup of flour, a little at a time. Once the flour is dissolved, take the liquid off of the heat, and incorporate the glow-in-the-dark dust gradually until the desired effect is achieved.
If using glow-in-the-dark chalk, place it in a sealed plastic bag, and hit it with a hammer on a solid surface until only small chunks remain. Then, place the broken-down chalk into a mortar and pestle, and grind the chalk into a fine dust.
For the wheat paste glue, a half cup of flour should be used for every cup and a half of water. Also, about four pinches of salt should be thrown into each cup and a half of water. After the water is boiling, add the flour in small amounts at a time, and whisk it into the water. Make sure all the flour is dissolved before taking the mixture off the heat.
Add the dust little by little, stirring it in until the desired glow-in-the-dark effect is reached. To test the glue, hold it next to a light source for 30 seconds, and then look at it in the dark.
