We added salt and stirred the ice and we saw the thermometer level move quite quickly down to -15c and then to -20 c. The ice cubes started to stick together.
What caused this to happen?
We know that salt causes ice to melt more quickly and it becomes slushy and colder. Rapidly melting ice absorbs heat more quickly and it becomes colder.

That is pretty cool learning, don't you think? What would happen if we ad a little bit of vanilla or chocolate flavour, milk and cream? I reckon it melts in your mouth...
