Equipment:
- A bowl of cold water
- A matchstick
- An ice cube
- Table salt
If you want to do this experiment, follow these instructions.
Place the cube carefully in the bowl (beaker) of cold water Gently place the matchstick lengthwise on the top of the ice cube Sprinkle enough salt on the ice cube with the matchstick Wait for 30 seconds Gently lift the ice cube to see if the matchstick was sticking on the ice cube like the matchstick was glued on the ice cube.
Outcome:
The ice was supposed to stick at the matchstick but in my group, it didn't stick to the matchstick. We probably tried about 7 times and it still didn't work.
Why did the matchstick stick on the ice cube?
It is because of the salt. When the salt goes into the ice, the ice will become colder and it will melt. So when it melts it will start to stick on an object, just like what happened with the matchstick. But unfortunately, it didn't work on us. But I hope you enjoy and I hope you learn something.
