28. DIY Gluep<\/b><\/span><\/h4>

Create DIY Gluep by mixing borax solution with white glue in a bowl. As the borax interacts with the glue, it forms long chains of molecules, creating a non-Newtonian fluid with unique properties. When pressure is applied, it behaves like a solid, but when left undisturbed, it flows like a liquid. This experiment demonstrates the principles of polymerization and viscosity in materials science.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
