1. The Chemistry of Bubbles
Mary Michael Lillicrap

2.  The pressure against the film
will be equal on both sides.

3. SHAPE
No matter what initial shape a bubble
has, it will always eventually evolve into a
sphere.
 Sphere occupies least surface area
 Less area= less energy
 Surface tension

4. All bubbles consist of 3
layers
 Soap-Water-Soap
 Hydrophobic VS
Hydrophilic hydrocarbon

5. Bubbles can merge
 Same size  Different size
*regardless of size they will meet
at 120 degrees.

6. Bubble “life”
 Unfortunately, all bubbles will
eventually pop once the layer of water
evaporates
 To extend the time of a
bubble, glycerin can be added to the
solution
 10 day bubbles?!
