Tactile Experiences

Use physical and tactile experiences to demonstrate intermolecular forces. For example, If you stretch a plastic grocery bag (made of polyethylene), the length increases and the width decreases. This breaks apart the London Dispersion Forces (induced dipole-induced dipole interactions) and straightens out the polyethylene chains. The covalent bonds remain intact until the plastic rips.
