The pepper and water science trick is one of the easiest magic tricks you can perform. You only need a few common kitchen ingredients to perform this science magic trick.
You need: black pepper, water, dishwashing liquid, plate or bowl
Pour water into a plate or bowl.
Shake some pepper onto the water’s surface.
Dip your finger into the pepper and water (to see that nothing much will happen).
However, if you put a drop of dishwashing liquid on your finger and then dip it into the pepper and water the pepper will rush to the outer edges of the dish.
*If you are doing this as a ‘trick’ then you might have one finger that is clean and another finger that you dipped in detergent before performing the trick. You could use a spoon or chopstick if you don’t want a soapy finger.
