Can anyone help pick out a science fair project in which I can experiment that is related to bubbles? Please keep it simple, and list the steps on how to experiment.

How can germs get past the cell membrane?
Get a bubble blower thingie(square works best) and two pencils. Dip the blower into a soapy solution and hold it up, then take the pencil and try to put it through the bubble. It pops. Now, take the other pencil, this time dip it in the soap solution and then put it through. This pencil goes through because this "germ" coated itself with a similar membrane, tricking the cell into letting it in.

Maybe do an experiment on shampoo. Test which one cleans more and why it does (ie, what chemicals does it have that helps it clean more). My friends/class mates did this in grade 8. They put ketchup in their hair and used different shampoos to see which cleans better. It may sound gross, but maybe you can use something else rather than ketchup.
Another experiment is using baking soda and vinegar. Explain why that chemical reaction happens.

since bubbles in boiling water is water vapor then you can do a project somewhere around that
maybe tests different liquids and see how long it takes for them to evaporate when they are boiling.
it will be faster since it is boiling so it won't take forever
then just come up with a analysis to why a certain liquid vaporized faster or slower
