Glass A has scissors.
Glass B has a paperclip.
Glass C has an eraser.
Glass D has a watch.
Most people focus on the water level, but the real question is: which object takes up the least space?
The bigger the object, the more water it pushes up. So a glass may look fuller while actually holding less water.
👇 Answer:
Glass B has the most water because the paperclip takes up the least space.
