Plastic rice beads are available online and at some art supply stores. They're used to cushion shipped cargo and for crafts projects. When you conduct your experiments, you could compare a sample of plastic rice with the rice you want to test. Some people have seen videos of plastic rice beads being produced and assume that they're made just to be passed off as food. However, plastic rice beads are more expensive to produce than actual rice, so it wouldn't be profitable to try to substitute plastic for the real thing. If you just want to test a small amount, drop a tablespoon of rice into a glass of water. To test a larger batch, add the rice to a large pot and cover it with 2 to 3 inches (5.1 to 7.6cm) of water. If you're also testing a sample of plastic rice, add it to a separate container of water. Mix up the rice and water for a few seconds. Then give the mixture about 30 seconds to stop swirling. Because of its density, rice sinks in water. If any grains float to the surface after the water settles, you should be suspicious. The difference will be obvious if you're also testing a sample of plastic beads. You might see bits and pieces of dirt and other debris float, but all the grains of rice should sink. Aside from verifying its authenticity, soaking and rinsing rice before cooking removes impurities and helps separate the grains. In the end, you'll have a fluffier, less sticky bowl of cooked rice.

summary: Purchase plastic rice beads if you want a comparison. Add rice to a glass of water. Stir the water and let it settle. Look for grains that floats to the surface.

Place a directional or table lamp beside the trap. Before bed, turn on the lamp and position the bulb above the trap, so the light shines into the trap. The fleas will be attracted to the light and warmth, and when they jump toward the light, they'll land in the trap below. Use an incandescent or other heat-producing bulb for your trap to attract the most fleas possible. Make sure the lamp is sturdy and not at risk of being knocked over into the water. Use this attractant only in rooms where you can shut the door and keep people and pets out while the lamp is on. Fleas are, for some reason, twice as attracted to yellow-green light as they are to other colors of light. You can increase the efficacy of your lamp attractant by using a yellow-green bulb, or by installing a yellow-green filter on a lamp with a regular bulb. You can buy colored light bulbs at many department and superstores. You may be able to find filters and gels at camera and art supply stores. You can also use a tea light to create light and warmth that will attract fleas to the trap. Place a tea light or votive candle at the center of the trap, and light the candle before bed. As the fleas try to get close to the source, they'll fall into the trap and drown. Place the trap away from walls, drapery, and other flammable objects. Always exercise great care and proper fire safety measures when burning candles. Close off the room to prevent people and pets from entering when the candle is lit. Fleas are attracted to carbon dioxide, and this is part of the mechanism they use to find a host. Because plants release carbon dioxide at night, placing one beside the trap may help to attract more fleas. Dormant flea pupae are particularly sensitive to carbon dioxide, so this may be a great way to catch young fleas before they have a chance to lay eggs.

summary: Use a lamp to attract fleas. Use a yellow-green filter on a light. Place a candle in the center of the dish. Place an indoor plant beside the trap.

Rating your anger can help you realize what type of events make you angry and the degree they make you angry. Some events might cause mild irritation, while others might trigger you wanting to blow your top. You don't really need an official anger scale. You can make your own, for instance, on a scale of one to ten, or zero to one hundred. You can use what works with you. Your anger journal will help you keep track of what events anger you. You can also track the degree to which they anger you, as well as the surrounding events that preceded your anger or occurred during your anger. Monitor how you react when you're angry, along with other people's reactions to you. When you record in your journal, you can make the following observations: What provoked the anger? Rate your anger. What thoughts occurred as you got angry? How did you react? How did others react to you? What was your mood right before it happened? What symptoms of anger did you feel in your body? Did you want to leave, or did you want to act out, such as bang the door or hit something or someone, or did you say something sarcastic? What were your emotions immediately after the incident? What were your feelings a few hours after the episode? Was the episode resolved? Keeping track of this information will help you learn what situations and triggers you are sensitive to. Then you can avoid those situations when possible, or predict when these situations occur if they are unavoidable. A trigger is something that happens or that you experience that brings on an emotion or a memory. Some common triggers for anger are: Not being able to control other's actions Having other people fail to meet your expectations. Not being able to control daily events, such as traffic. Someone trying to manipulate you. Getting mad at yourself for a mistake. Sleep deprivation can mount up over a series of poor nights of sleep or can be caused by not getting sleep for one night. Your metabolism, age, personal willpower and other personal makeup will all determine how you respond to sleep deprivation. The following effects can all contribute to your difficulty in keeping your temper in check: Increased susceptibility to accidents (due to poor coordination and sleepiness) Increased susceptibility to colds Rapid aging Emotional problems (loss of control, anxiety, panic, depression) Irritability, moodiness, reduced ability to cope with stress Poor judgment skills, poor concentration, and inability to make decisions Long-term effects of sleep deprivation may include obesity, heart disease, or diabetes.
summary: Rate your anger. Keep an anger journal. Identify your anger triggers. Understand the possible effects of sleep deprivation.
