Let’s take this outside!
Fill two identical glasses with the same amount water. Use a marker to draw a line at the height on the water levels.
Find two solid, nonporous objects. Gently drop your first object into the glass. Use a marker to mark where the line rose. Repeat for the other object.
Use a ruler to measure the space between the first line and the second line for both glasses. If they measure the same length, the volumes match.
