Article: Cut a 1⁄2–1 in (1.3–2.5 cm) section from a wire hanger if you want a dart-like projectile. Otherwise, you can use a BB or ball bearing as your projectile. Feed the projectile into the barrel of your coil gun. You can use any projectile as long as it’s magnetic. Place the battery back in its terminal so a current can run through your circuit. Locate the triangular metal piece on the back of the circuit and press down on it with an insulated screwdriver. Hold the screwdriver there for 5 seconds so the capacitor can fully charge. Don’t touch the capacitor after it’s charged or else you will get shocked. Once the capacitor has been charged, flip the switch into the on position to shoot your gun. Turning on the switch completes the circuit and charges the coils around the barrel, propelling the projectile forward. Once you shoot the gun, leave the switch on for 1 minute so any leftover voltage in the capacitor can discharge safely. Make sure your gun isn’t aimed at any living thing since it will shoot quickly.

Article: A microwave-safe pie dish works well, but any dish marked safe for microwave use will be adequate. Only add enough walnuts to cover the bottom of the dish in a single layer. Keep the walnuts in halves or quarters to ensure the best possible toast. Check the walnuts to make sure that none have burned. Stir them using a heat-resistant spatula to make sure that each nut is getting cooked evenly. If your microwave does not have a rotating tray, turn the dish 180 degrees before continuing. Smell them to see if they have finished cooking. If done in the microwave, walnuts will not brown, but the toasted smell should still come through. This will not usually be necessary after the first 2 minutes of cooking, but it might prove useful if the halves are especially large. Eating them directly out of the microwave could cause you to burn your mouth.

Place the walnuts into a microwavable glass bowl. Microwave on high for 1 minute. Cook the walnuts for another minute on high. Microwave in 20 second intervals as needed. Let the walnuts cool slightly before serving.
Article: Make a decision based on what it is you plan to use your credit card for. There are many different kinds of credit cards. Here are just a few:   Standard credit card. Do you want a card to increase your monthly buying flexibility? Maybe you're just tired of handing out cash or going to the ATM every second day. These credit cards come unsecured, which means that you don't need to put down a security deposit to prove you can pay your debt off.   Rewards credit card. Do you want to earn rewards with a specific retail store, gasoline company, or airline so that you can redeem your points for clothes, mileage, or vacations?  Business credit card. Do you need to open a line of credit for your fledgling small business? Business credit cards come with special bonuses that might appeal to a business owner. Figure out which type of card is best for you by what their interest rates are and what specific benefits the company offers before choosing one. Some things to keep in mind include:   Annual Fee - Many companies charge between $15 and $50 for use of their card. This fee can sometimes be waived if you are a frequent user of the card, transfer a specific balance to the card, or, sometimes, just for asking!  Annual Percentage Rate (APR) - APR is how much money in fees and interest you can expect to pay on top of the principal that you borrow. If you pay $50 in fees and interest after spending $500, your APR would be 10%. Your APR can be either a "fixed" or a "variable" (floating) rate. Fixed rate generally are a little higher, but you will know what to expect each month. Variable rates are based on a current published index coupled with an additional percentage.    Grace Period - This is the amount of time between when your transaction is posted to the account and when interest begins to be charged to it. This is usually 25 days from billing time, unless you carry a balance.  Late, over-the-limit, and account setup fees - Most companies charge you late fees (for paying your bill late) and over-the-limit fees (for going over your credit limit), but it is very rare for a company to charge an account setup fee. Your credit score is a score on a scale from 300 to 900, with 900 being the best. This number is used to express an individual's creditworthiness, or how likely s/he is to repay a debt. 650 is an "average" credit score, while anything above 700 is considered great and anything below 620 is considered poor. Your credit score will affect your ability to get a credit card. Studies show that people who use credit cards tend to spend more than people who use cash. Scientists think that the experience of parting with real money in real time is fundamentally different from the experience of pledging to part with real money at a later time.  Scientists also know this: people who buy a laptop, say, with a credit card are less likely to remember details about its costs than people who pay for the same laptop with paper currency.  Finally, you don't need a scientist to tell you that getting a credit card means giving yourself the opportunity to buy something you can't afford. This is not necessarily a bad thing, but, for financially irresponsible people, it can have devastating consequences. Locate online applications or a hard copy of an application and look over the information on interest rates, grace periods, penalties, and rewards. The abstract information credit card companies publish can be a lot different than the nitty-gritty stories told by people who have actually dealt with those credit card companies in real time. As mentioned above, some credit cards come with miles that you can use on flights and other incentives. Some credit cards, however, give out reward points only after you spend a certain amount, making the deal a little less sweet.  According to the federal government, about 46% of American families carry credit card debt. Since people who sign up for rewards programs tend to spend more money than credit card users without rewards programs, it's probably best for individuals with high debt loads to stay away from rewards programs. In any case, do not let the promise of rewards drive your spending. This is what the creditors count on, so don't fall into this spending mode.—Instead, consider the rewards as a bonus or surprise which may help to defray the cost of purchasing on credit. For example, if a credit card offers cash back rewards for gasoline purchases made using their card, it might make sense to use that credit card for all of your gasoline purchases, but not to change your spending habits. In the end, using this strategy, your gas purchase price will have been reduced.
