Sodium Silicate Polymer Lab

My hypothesis for the lab was that the two liquids would come together to make a solid and when it was tested it would bounce higher than the borax polymer. When forming the borax polymer the combination acted like Play-doh and formed together easily, but the silicone polymer took much more pressing and kneading to form. When the two liquids, silicone and ethanol, mixed together they became like a gel and with more mixing became a crumbly clear-white mess. When I squeezed it into a ball some liquid was squeezed out too, which i believed to be the ethanol. Compared to the borax polymer, the sodium polymer bounced up 15 cm at room temperature compared to 9. When the sodium polymer was chilled and bounced it only went 10 cm and the borax went 6 cm up. My hypothesis was correct but the way the liquids formed a solid was unique and very different than i thought it would be.
