All that experimentation floating candy in soda got me thinking: can we test how soda floats? The perfect opportunity presented itself at my husband's work party, where we found a tub full of choices. I held up one can of regular Coke, and one can of diet, and released them at the water's surface. Diet Coke bobbed away, while the regular Coke sank to the bottom.

This was so fun I tried it with many kinds of soda, and only stopped when I couldn't feel my cold fingers anymore!

Summer Soda Experiments

After testing what kinds of candy float in which kinds of sodas, my children examine the results while sipping leftover test solution.
