Materials: Fork, water, Olive oil, 2 plastic see-threw cups, detergent.
Method: Firstly you get your 2 see-though cups and put the water in both up to its first ridge then pour the oil into both up to the second ridge after that get the detergent and pour into only one of them to the third ridge next stir the fork around the cups at least 10 times and it will become bubbly the more you stir
Observation: When the oil is put in the cup there are two layers which was only the water and oil then when the detergent is put in it fuses together after time and after 10 stirs of the one without detergent does not change. The one with detergent one also becomes bubbly.
