Sodium Silicate Polymer
Question: What will happen after Calcium silicate and ethanol are combined?
Hypothesis: It will create a bouncy substance that is thicker than the previous polymer we created, similar to that of a bouncy ball.
Results: We created a mixture using roughly 12ml of Sodium Silicate, and 3ml of Ethyl alcohol. At first, the mixture was very crumbley and loose. It would flake apart with the slightest contact. My lab partners and I discovered that you take the flecks of the mixture, which resembled hail at this point, and slowly applied pressure to push them together. It took many tries to get it right, because if you applied to much pressure to the mound, it would suddenly break apart, or if you applied too little, it would just fleck off. Several of the test we conducted included a bounce test. This is where we dropped the bouncy ball from roughly three feet in the air, and it rebounded to roughly 40% of its start hight. Another test we conducted was an elastic test, in which we concluded it is not as elastic as our first polymer, which was stretchy and goo-like.
Conclusion: In conclusion, this polymer was more bouncy, but not as elastic as our first polymer. Even the smell was different. This one was also smaller, and was harder to form. It required a great deal of attention to make sure the creation did not fall apart. It held the same basic procedures as the Slime Lab, but the outcome was rather difficult. This was to due with the compounds we were using, since all materials bond a little differently.
