What is a simple experiment to determine the permeability of cheesecloth, plastic wrap, latex rubber, and sati

Stretch the material being tested across a toilet bowl, then put down the seat.  When someone uses the convenience, they will be happy to inform you about the permeability factor, though their descriptive terms may be subjective.

1/8 cup borax laundry detergent\n1 1/2 cup hot water\n1 cup white elmers school glue\n1 cup hot water \nMix borax with hot water. Stir until dissolved. Mix glue and water. put 1/2 cup plus 2 tablespoons of glue mixture in a medium Ziploc bag and add 2 drops food coloring. Add 1/4 cup borax mixture. Squish the bag to mix the ingredients well. Soon you'll have a slime. Put in small containers overnight. Children have a lot of fun playing with it and it's not messy

Assuming a pure substance, (this method will not work on mixtures).  \n1. Dissolve in Carbon disulphide.  (The compound is now banned in schools)\n2. Allow to evaporate in a fume cupboard.\n3. The presence of yellow rhombic like crystals is a test for S.\n4. Melt a sample and do a MP test.\n5. Melt a few grammes and allow to cool in air.  Needle like crystals will be formed.

air resistance.\n\n Do the experiment yourself- if at school- get a teacher to make up a sealed tube, suck out the air (less difficult than it sounds- i remember doing something like this) and then invert it. its very strange.

Well.......here goes. This experiment relies on the solvent solution being absorbed into the paper, and climbing upwards. This then allows the separation of the test material / substance, which follows the solvent solution. Most solvents will quickly evaporate when introduced to the air, so for more accurate results, and an overall truer picture, the container should be sealed.

It should be clarified that the idiot 4 posts above this one is wrong. There are no pores in latex condoms, they do not allow anything through. Think about it, scientists at the Center for Disease Control use latex gloves... so latex is good enough for this job. Latex condoms are the MOST effective way to prevent the spread of HIV and other Sexually Transmitted Infections. Always use a condom.\n\nAlso, when used correctly, condom breakage is non-existant. Breakage happens when the tip is not squeezed to evacuate air, or when two condoms are used at once. Two is NOT better than one. Condoms should also be changed after 15 minutes of use.

now are you talking liquid latex or cloth like latex.  i would do a search on liquid latex.  my room-mate bought some when we threw a lingerie party.  that was pretty fun stuff.

Boil ¼ cup of water. Add one teaspoon of gelatin and one teaspoon of\nsugar. Stir for one minute until everything is dissolved.\n2. Cool the solution for ten minutes.\n3. Fill a petri dish to a little below the top edge.\n4. Close the petri dish by putting on the cover immediately. Let the\ncovered petri dish stand for at least four hours. Don’t touch the\ngrowth medium or you’ll add your own germs!\nThis recipe will fill two, small petri dishes. If you and your class plan to fill\nmore petri dishes, make more germ food by increasing the amount of your\ningredients proportionally.\n*Adapted from Gross But True Germs by Luann Colombo. See details in bibliography. If you don’t\nhave the materials needed for the experiment, you can purchase Ms. Colombo’s book, which includes\nall the supplies needed to conduct the experiment.
