The glass transition is difficult to visualise, so what better way is there than to smash some frozen Jelly Babies? In this video, Pharma Drama brings the glass transition temperature to life with liquid nitrogen, a rubber band, a packet of Jelly Babies and a hammer! You can see a more detailed description of amorphous materials here;

Thank you so much . However i have a question. why doe the jelly baby not re-transform to its rubbery state when it is heated up again after being removed from liquid nitrogen again like the elastic band. And can the elastic band be broken straight after being removed from liquid nitrogen?

You raise some good points! The Jelly Baby will indeed return to its jelly state if warmed up and won't explode with a hammer. Less good on camera, but I should perhaps have included that. The same is true for the rubber band - while brittle, it will break.
