Q: You will need a light source and a spectrophotometer. These are available in science lab supply stores. The spectrophotometer will have instructions for the proper usage of the model you bought. This equipment is inexpensive and easy to use, so this is one of the more common methods for measuring bacterial growth. In layman's terms, turbidity is how cloudy your sample is. You should get a turbidity reading, which is measured in NTU (Nephelometric Turbidity Units). Your spectrophotometer may take some calibration before you can accurately measure the turbidity of your sample, so consult the manufacturer's reference manual prior to use. Turbidity corresponds to the amount of bacteria in the sample. The spectrophotometer will also tell you the percent transmission (%T). This number will be higher if the turbidity is lower. Compare your numbers from different tests to measure bacterial growth.
A: Get the necessary equipment. Shine the light through the sample. Make some notes.

Article: Begin with a diamond shape that has rounded edges. It needs to be it about 9 inches (22.86 centimeters) high and 8 inches (20.32 centimeters) wide. Cut the template out when you are done. Make the top and bottom corners a little wider. They should be about 2 inches (6.35 centimeters) wide. This will be the exterior of your cloth pad, so choose something that you like. You can use patterned fabric or a solid color. You can even use a pattern for one side, and a solid color for the other. You can also use cotton fabric instead of flannel. Check out the quilting and calico section of your local fabric store for lots of colorful options! Pin the two pieces together first, with the right sides facing in. Sew around the piece using a -inch (0.64-centimeter) seam allowance. You do not need to leave a gap for turning because you will be cutting a slit into it. Make sure that you are only cutting through one layer of fabric, not both. Position the slit right in the middle. It only needs to be a few inches/centimeters tall. Consider cutting notches into the curved corners of the pad. This will help reduce bulk. Use your fingers to push the corners of the pad through the slit that you cut. If the edges/corners didn't turn out all, push them out with a pencil or knitting needle. Press the pad base with a hot iron using the cotton setting. You can use a matching thread color or a contrasting one. You can even use a zigzag stitch to make it look more interesting. Backstitch at the start and end of your sewing, then trim the excess threads of as close to the fabric as you can.
Question: What is a summary of what this article is about?
Create your template on a sheet of cardstock. Use the template to cut two pieces out of cotton flannel. Sew the two pieces together with your chosen sides facing out. Cut a vertical slit in the middle of the piece. Turn the piece right-side out through the slit. Topstitch around the top of the pad base.

Q: You could get dessert at the same restaurant where you eat, or go to a different place to wind down the night. No matter what type of date you had, it's nice to incorporate something sweet at the end. It is one last thoughtful touch that shows your date you put a lot of thought into planning the evening. Plus, it gives you the opportunity to share a dessert, just like in the movies. Going out for ice cream is a nice way to end a date during the summer. If you're cooking at home, consider serving something with chocolate. It tends to be a favorite. If your date does not have a sweet tooth, you could go to a bar to grab a nightcap instead. Of course, if you or your date do not drink or are underage, this is not a good idea. Sometimes an individual cannot have rich desserts, especially those with diabetes. Or the person may have allergies, food sensitivities, medical conditions, or whatnot. Just be flexible and understanding. The end of a date can be a little awkward if you have not thought about it beforehand. Put some forethought into your plans. Are you going home separately after dinner? Do you plan to drop your date off after you're finished with dessert? Perhaps you may like to invite the person back to your house. Think about the logistics so you avoid that awkward "what now" moment after an otherwise perfect date. Have your house ready in case you end up there. Have it clean and presentable. A kitchen with last night's dishes stacked in the sink and your dirty laundry in a pile on the floor will likely make a negative impression. End the date at a good time. Ending a date on the right note is tricky. In general, end it at a logical moment. For example, after the late movie ends, offer to drive her back to her place. It is generally better to end the date a little on the too early side than too late. Kiss, hug, or more? At the end of a date, especially a first one, generally a gesture will effectively end the date. This is sometimes a very awkward moment. Generally in a heterosexual date, the girl should decide what she is comfortable with offering the guy as a gesture. If something goes awry, remain calm and work towards having a good date anyway. A person who is inflexible, stresses out, and becomes irritable in the face of the unexpected will not be very successful with dates. In fact, dealing with the unexpected in a creative, positive way can make a big impression.
A:
Don't forget dessert. End gracefully. Go with the flow.
