What You Did
You melted an ice cube in water.
When the ice cube melts, the water level doesn’t rise.
Your results will be skewed if you measure add ice after you measure the water line.
Try the original experiment: place ice in a cup, then use another cup to fill it to the brim with water. When the ice melts, does the water overflow out of the cup?Try adding water to a bunch of ice cubes all at once
