Playing with poisoned milk is divided into two steps:

　　Step 1: Prepare. Prepare a small container with a layer of sponge inside, and fill the container with cooked poisonous milk, and the sponge should be soaked with one and a half minutes of poisonous milk; The white mouse prepares a large table tennis racket and a table tennis ball. Before the game, the table tennis ball should be put into poisonous milk and let him soak it a little. In addition, prepare a pile of radish and fur toys;

　　The second step: the game. Take out the fur toy, put it in the poisoned milk container, and let the white mice play; In addition, table tennis will float in the container, so white mice should take it away as soon as possible, and then move the radish in the container; Give the white mice some time to play, and then clean up the poisoned milk and its toys safely so as not to let them eat the poisoned milk.
