Plasticity Conclusion

In science class, we did a lab about "Plasticity" and what we did mix cornstarch and water together.When I mixed the cornstarch and water together in a bowl and had to mix it together until i became hard.When I picked it up the heat from my hand made it become hard and when I released the tightness of my hand it became more like a liquid.While it was in he bowl I poked at it and it had turned more of a solid around my finger and when I would take my finger away it turned back to a liquid, which was kind of WEIRD!.By doing this experiment, I get a better outlook on how the earth's mantle works.Inside the mantle, molten magma is being churned, which makes the litospheric plates moves and they cause earthquakes.The earth would probably not be what it is today without plasticity.
