Soda Bags
When I did the cans we had lots that were less dense then water. We found in my class that measuring out a volume of soda and rendering flat worked a lot better for looking at soda densities. Also in a regular sandwich ziplock two small paper clips neutralized the plastics buoyancy. Side note Coke zero is neutral.
This also allows you to buy 2L bottles instead of cans.

Hi Bryan,
I like that idea. There was alot of wasted money in cans of Coke that didn't sink like we wanted them to! It would be much more cost effective to use 2L bottles and bags! I might actually try that... otherwise the lab is just too expensive. Thanks for the ideas!

Cool idea! The plastic's buoyancy was annoying me! Did you trim the tops of the bags like in the workshop?
