We had some fun this Saturday with this experiment. Hunter absolutely has a thing about bubbles. Every chance she gets she wants to play with bubbles. But the pre-made shop bought bubble mixture can be rather expensive and goes like greased lightning the way she plays with them!!! So I decided to try out my home made recipe and see how we go.
Water sandwiches part 1
We made two mixtures to see which works the best. I call bubbles "water sandwiches" and I will explain why very shortly.
Water Sandwiches Recipe
1 cup of dish soap ( keep the bottle handy in case more is needed)
Distilled water or tap water.
1 cup of corn syrup (but be very generous)
bucket or container with a lid.
Distilled water or tap water.
1 cup of corn syrup (but be very generous)
bucket or container with a lid.
We made two batches. One with distilled water and one with plain tap water to see which would work better.
Method
1) Place all the ingredients into the bucket.
2) Stir.
3) For sweet results, let the mixture sit overnight. Unless you have a five year old screaming
in your ear 'BUBBLES!!!!!!" over and over, a hour standing time should be suffice.

Dropping The Science:
Bubbles are made up of three layers: soap, water, soap. The layers of soap on the outer and inner part of the bubble is called a soap film. (Wow, how original!) The middle layer that the water resides is trapped between the soap film "sandwiching" the water in place. When the layer of water evaporates, the soap film becomes unstable and collapses, also referred as "popping the bubble". The stronger and thicker the soap film skin, the less chance of the water sandwiched between the layers evaporates. That is the key for longer lasting bubbles!
