Write an article based on this "Design an experiment. Carry out the experiment. Troubleshoot if necessary."
article: An experiment is a test, or series of tests, to disprove your hypothesis. If the experiment fails to disprove your hypothesis, that means that it may be suitable for making predictions about the question you have posed. If the experiment disproves your hypothesis, it means that the hypothesis does not accurately predict the outcome of the situation. You might decide that your experiment will be to shop at Store A and Store B and compare the money you spent at each store. Once the experiment is laid out, you will need to carry out the steps. It is important not to carry out the experiment with bias. The scientific method does not allow for tweaking the experiment to make the results fit what you want. For example, you must commit to buying the same foods at each store for a fair comparison. You should not buy the name brand at Store A, and the off brand at Store B to draw the conclusion that Store B is cheaper. In this scenario, the foods serve as your control and the stores are your variables. Sometimes, experiments do a poor job of testing the hypothesis. When this happens, you have to troubleshoot your experiment. Ask yourself what went wrong, and how can the next experiment address these issues. For example, you could compare receipts from each store and think that you are saving $15 per week, but you only notice an extra $5 per week leftover. Upon a closer investigation, you realize that you have to buy extra gas each week to get to Store B, and that detracts from your savings. At this point, you would need to redesign your experiment to include gas receipts as well.

article:
Take a kitchen sponge that you don't plan on using for washing dishes anymore. Run the abrasive scrubbing side against the clothing or blanket to swipe off pet hair. Do this outside or over a trash bag so you don't get hair all over your floors. For hair that's tough to get off, you can use a damp sponge. Wet the sponge, then wring out any excess water before brushing the fabric. Start with a clean adhesive sheet on your roller. Then roll it over the item, using smooth strokes in one direction. Pay special attention to any areas with a lot of hair. Rip off the sheets as they become covered in hair to expose fresh sheets. Otherwise, the roller won't be as effective at pulling up the hair. You can also loosen the hair before using the lint roller by spraying static guard on the fabric. The warmth and moisture of the steam also releases trapped hair so it will be easier to remove in the wash. Fill the tank of the steamer with water, then lightly run the steamer over the fabric in downward strokes. Steamers are safe to use on delicate materials, like wool or velvet. Check the care instructions on the label of the item if you aren't sure. It's easier to steam items when they're hanging up. If you're on a budget, you can buy a handheld steamer, which typically costs around $30 to $40, instead of a standing steamer, which can cost over $100.
