Which wood glue is stronger?

Wood glue is widely used at homes and businesses for construction or repair of wooden products. Wood glue is also used in connecting processed wood products such as papers and cardboards. 

Many different materials have traditionally been used as wood glue. Some of such materials were extracted from animal and plant products. Modern wood glues are synthetic resins similar to plastics. 

Not all wood glues are made of high quality resins. Some manufacturers use less glue in their products and add more water and more thickening material in order to reduce the cost. 

 Project description:
In this project you will perform experiments to compare different wood glues for their strength after they dry.
