Materials Required:
l Light-coloured bowl
l Water
l Paprika
l Dishwashing liquid
Procedure:
- Fill a light-coloured bowl with water and shake some paprika evenly over the top of the water.
- Put a drop of dishwashing liquid on your finger, then dip your finger into the center of the bowl. The red paprika quickly scoots to the sides of the bowl.
This Is What Happens:
Dishwashing liquid is a detergent, and one of the important qualities of detergent is that it mixes easily with water. As you dipped your finger into the bowl, a small amount of dishwashing liquid from your finger readily attached itself to the water. Then it quickly spread over the entire surface and pushed all the grains of paprika to the sides.
