Diet vs Regular Soda Float Test

One may float while the other sinks. Ask students to predict what will happen. Place both cans in water. Key idea: Dissolved sugar adds mass; similar volume gives different average density. Ask: What is different inside two cans that look the same? Safety and cleanup: Wipe cans/tub; no drinking after demo. https://www.google.com/search?q=%22Diet+vs+Regular+Soda+Float+Test%22+science+demonstration+experiment
