The document discusses the chemistry and properties of bubbles. It explains that bubbles will evolve into a spherical shape because this shape occupies the least surface area and requires the least energy. All bubbles consist of three layers - soap, water, and soap. Bubbles can merge regardless of their initial sizes and will meet at an angle of 120 degrees. Eventually, all bubbles will pop once the layer of water evaporates, but adding glycerin can extend the lifespan of bubbles up to 10 days.

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?!
