Science project trouble Invention glue by foam is happen by foam is change to glue by gasoline. We are make science project board by many foam in this work. And we work always surplus many form. We think about many form bring applied. Surplus of form have more valuable than garbage. Because the science project board is use many glue. But glue is expensive. We think the project about the invention of glue by form makes many foams valuable and decreases garbage. For we want to receive to education and compare quality glue from surplus foam and original glue. Hypothesis of receive to education have manage by bring foam and gasoline put in the jar, close the jar and seal for about 3-4 weeks. Afterwards put into practice compare with original glue. Overall operation invention glue by foam is closely similar to original glue. We make to a précis form and gasoline invention glue by foam are closely similar original glue.
