Glue Stick
Glue Sticks: Use a 40 g, permanent, clear, non toxic glue-stick. The sticky material in a glue stick is a gel.

A gel is a solid, jelly-like soft material. Gelís can be soft and weak to hard and tough.

They can dry out quickly if the cap is left off for a period of time so always remember to put the cap on when not in use. 

You can apply the glue by holding the open tube vertically in the middle of your paper and moving to the outside edges. Make sure to cover the whole surface. 

Keep your fingers clean and always put the cap back on immediately. If you donít, the glue will dry out quickly!
