Put an ice cube(冰块) from your fridge into a glass of water.You have a piece of ice with the help of the string.But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together.There is a salt-cellar(盐瓶) on the table.You must use salt when you carry out this experiment.
Frist,you put the string across the piece of ice,and then put some salt on the ice.Salt makes ice melt.The ice round the string will behin to melt.But when it melts,it will lose heat.The
cold ice cube will make the melted water freeze again.
After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
this experiment can be very useful to you.For example ,if there is ice near the door of your house,you may use much salt to melt all the ice.If you don't put enough salt,the water will freeze again.
