Can Candy Bars Float?

Question:  
Why would a candy bar float?

Research:
If something is more dense than water, it will sink.  If it is less dense than water, it will float.

Hypothesis:
Candy bars cannot be less dense than water, so they should not be able to float.

Experiment:
Materials:  Water, Clear Bowl, and Various Candy Bars (3 Musketeers, Snickers, and Milky Way)

Procedure:
1. Fill the clear dish with water.
2. Unwrap one candy bar.
3. Drop the candy bar into the water. 4. Make notes as to if it sinks or floats.

Will the Milky Way float?.... NO!

Will the Snickers float?...No!

Will the 3 Musketeers float?  YES!!!

Analysis:
The 3 Musketeers must have air bubbles in the middle of the candy bar, so it is less dense than water

If holes are poked in the 3 Musketeers, air bubbles escape.  IT IS LESS DENSE THAN WATER!

Conclusion:
The appearance of something does not tell if it is able to float.  It is what's inside it.  If there is trapped air, it will float, no matter the size.

This was the most fun science experiment!  I got to eat the supplies!
