Mantle Lab

On tueday we performed a lab during science class that showed how the mantle acts as a liquid but is a solid. First we mixed corn starch and water togeher in a beaker. Second we took the mixture out of the beaker and put it in out hands. If i were to roll the mixture in my hand fast the mixture would become hard like clay. If i were to lay it still in m hand it would melt but ot turn into a liquid. It acts like a liquid by melting but is hard like a solid. The texture of the melting mixture was like playdo. The resemblance that the mixture has of the earths mantle is that it is a very weak solid. The mantle is a solid layer but acts like a liquid. This lab was surprising and very cool. I did not expect the mixture to melt in my hand.
