Can you get an ice cube out of water without getting your hands wet?
Materials:
- Salt
- Drinking glass
- Water
- Length of string
- Ice cubes
The experiment steps:
1) Fill the glass with water
2) Place an ice cube in the glass
3) Dangle the end of the string on the ice cube
4) Keeping the string still sprinkle some salt on the ice cube and wait a few minutes
5) Now lift the string and watch as the ice cube comes with it!
You’ve gotten the ice cube out without getting wet!
Why did it happen?
So why did the ice cube magically stick to the string? Well its not magic at all, salt freezes to ice helping to make objects stick to it.
That’s why in winter it’s always a good idea to sprinkle salt on icey steps because it will stop you from slipping when you walk.
