u can show it eith the help of an activity also which is as follows:-

1) take a metal scale.
2) pour some melted wax drops on it.
3) then stick some iron nails on the drops of wax.
4) then heat the metal scale from one end.
5) invert the scale such that the nails would point downwards.
6) after some time u will observe that the iron nails falls down in a sequence.
