    </div>Not so bad!<br><br><br>So I went along and made two preparations, one from stretched rubber and one from relaxed rubber.

    <br><br><br><br>The result is stunning! See the coiled up fibres (those can't be the polymers, you need an atomic microscope to see those):<br><br><br><br><div style="margin:auto;text-align:center;width:100%">

    I would like to compare the different types of elastic on a micro level. Basically just for the fun of it, and out of curiosity.

    would be interesting to see a before and after on some flat band elastic that has been treated in various ways ( benzine , heat etc ) to see if the molecular structure changes much <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1">

    I love it! That is so cool! I just love the science behind elastic, I'm actually pretty sure I am going to do my Physics class' final project on the science of slingshots. Thanks!<br><br>Patrick <br><br>God Bless
