Science experiments you can try at home! Justin Huffman from Penn State Altoona’s Lions Learning Lab is taking us Ice Fishing!
This science demonstration teaches kids about freezing point depression of water with table salt, through the fun activity of picking ice up out of a container of water using only string.
- Ice cubes
- Table salt
- String (yarn or kite string works well), but any string will work.
- Chilled water from the refrigerator
- Scissors (parental supervision advised)
- Small container to hold the water and ice (could be a cup, bowl (plastic or glass), …etc.
- Attach a piece of string to the end of a pencil and fray the end of the string.
- Add chilled water to container.
- Add ice cubes into the water.
- Place the frayed end of the string on the surface of the ice cube.
- Add a small amount of salt on the surface of the ice cube where the string is touching.
- Wait about 20-30 seconds, or until the string sticks to the ice and then pull it out of the water. You caught an ice cube!!!!
