plastisity conclution

When my partners and I were doing the experiments we first had to put the corn starch in to the the beaker and then put water in to the beaker and then we had to try and mix it with our hands when we picked it and put it our hands it was liquidy but when pusher is put on it, it was hard. This relates to the inner of the earth because when the crust and the mantle were together the liquid was hard because presser was put on it, it turned hard but when the mantle and the crust is off a little bit the liquid is liquid.
