Conclusion

Today in class we did a lab using cornstarch. The point of the lab was to show how the mantle works. The cornstarch made the water thick and gooey. It also had plasticity. It was both a solid and a liquid. It was a solid when you put pressure on it just how the core puts pressure on the mantle. Its a liquid when you let go because it makes it all watery. When you push on it with your finger going fast it does not do anything and when you push slowly it goes in right away. This was by far the best lab we ever did, also the coolest.
