Fun Science Experiment
This video features a magic trick you might have already seen before: water disappearing from a cup. But the water doesn’t truly disappear with magic. Instead, this video explains how to do the trick with science. It is a fun science experiment you can do with items you might have lying around the house like diapers and water. The experiment teaches about Sodium Polyacrylate or Water Lock and how it changes the water into a solid-like substance in a few minutes.
Required Materials: –
- A glass
- Diaper
- Spoon
- Water
- Scissors
Procedure: –
- Cut the disposable baby diaper open with scissors.
- Collect the moisture holding material Sodium Polyacrylate.
- Put the sodium Polyacrylate in the glass and pour some water in it.
- After 2-3 minutes, you will see that the water starts changing into a gel like substance.
Concept: –
The particles in Sodium Polyacrylate have a property known as being hygroscopic. These particles absorb and hold water.
