- Butane cylinder                             
- Salt                                                 
- A container with water                 
- A thread of wool                           
- An ice cube.                                   

PHYSICHAL CHANGES   
-Fold (we folded the thread)
-Freeze (we freezed the ice cube)
-Warm up (we warmed up the ice cube)

BUTANE CYLINDER: we used it for warm up the ice cube
SALT: we used it for freeze the ice cube with the thread
A CONTAINER WITH WATER: we used it to put the ice cube in it
A THREAD OF WOOL: we folded it to hook it to the ice cube with the help of the salt
AN ICE CUBE: we freezed it to hook the thread in it, and later we warmed up the ice cube for free the thread

1st step: Take the thread and stick one end of it into the ice cube.
2nd step: Add some salt
3rd step: Put all in the container and wait one minute
4th step: You’ll see that the thread and the ice cube are stuck
5th step: With a butane cylinder, warm up the ice cube to free the thread.
