Plasticity Lab Conclusion

In science class, we did a lab which demonstrated plasticity. Plasticity is the ability to retain a shape attained by pressure deformation. The mixture we created in the lab was a solid, with characteristics of a liquid, because it flowed like a liquid, yet it was in the form of a solid. At first, it was white, but after we added the food coloring, it turned green. It was sticky, rubbery, and looked like silly putty. When handled, at first it was hard, but then it started to drip off your hand like a liquid would. If you kept it on there long enough, it would dry up again. If you pushed your finger in fast, the mixture stayed about the same. But if you pushed your finger in slow, it sank fast. This mixture was similar to the Earth's mantle because the mantle needed heat and pressure to become a sphere, just like the mixture did. This lab was so much fun! It was awesome to play with the "silly putty." I wish I could do it again!
