You are also unlikely to have liquid nitrogen at home, or in your school. Copyright Instruction Video Instruction 1 Put on the safety glasses and gloves. 2 Place the rubber toy into the metal bowl. 3 Slowly pour liquid nitrogen over the rubber toy and wait for at least 15 seconds for the rubber to cool down. 4 Using tongs, take the rubber toy out of the liquid nitrogen and then break with a hammer. If you are running this with onlookers nearby you should cover the toy with a cloth first before breaking the toy to stop fragments going near the onlookers. 5 Get the Unit of Work on States of Matter here!

The liquid nitrogen has a temperature of -196 degrees Celsius and has the capacity to freeze substances that are normally pliable at room temperature. The extremely cold rubber can be very brittle at these low temperatures due to this elastomer entering a glass transition phase and therefore easy to shatter. Once the rubber has warmed up the rubber is again easy to bend and squish. Variables to test More on variables here Does it make a difference if the rubber toy is hollow or not? Try toys with different cross-sections Compare this experiment with cooling down toys with dry ice – does this have the same effect? Learn more!
