Ice Cold 14 September 2018
You will need;
- A bowl of cold water
- A matchstick
- An ice cube
- Table salt
Instructions:
- Place the ice cube carefully in the bowl of cold water
- Gently place the match lengthwise on top of the ice and try to lift the ice cube
- Put the matchstick back on the ice and sprinkle a little salt along the line where it touches the ice cube
- Wait for 30 seconds and then attempt to pick up the ice cube again
What’s the science?
When you put salt on the ice, it melts the ice and it also makes it colder, and that's why the matchstick stick on the ice
