Materials

Neodymium magnets

White glue

Sodium tetraborate decahydrate

Coloring agent

Silly putty

Iron powder

Staples

Clips

Procedure

1.Phagocytosis protocol

a)Knead the silly putty to make a ball and place it on a flat surface like a table

b)Carefully place the neodymium magnet in contact with the putty and wait 5 minutes

c)Observe how the silly putty slowly phagocytes the magnet

2.Magnetization protocol

a)Spread a few clips and staples on the table

b)Place the silly putty close to them. Nothing happens. The silly putty is not magnetic

c)Place the magnet in contact with one side of the silly putty for a short period of time to avoid phagocytosis

d)Pull the magnet apart and bring the clips and staples close to the magnetized area of the silly putty

3.Bouncing protocol

a)We are going to compare the properties of regular plasticine and silly putty

b)Make two balls the same size. One of plasticine and another of silly putty

c)Drop both balls and observe their different behavior. The one made of silly putty bounces while other does not
