Some industrious students are working to create a perfect liquid glue recipe. They mix 1 gram of Gl (a white powder) with 1 gram of Ue (a green powder) in 100 ml of water and shake the mixture well. The product is a very sticky blue liquid super glue with some of the original white powder at the bottom of the mixing jar. Whey they pour off the glue and dry and weigh the white powder they find that it weighs .5g.
