Article: Check the expiration date of milk when you buy it at the store. Choose milk that is farther from its expiration date. Older milk has more glycerol, a natural compound that makes it harder for frothed milk to hold its bubbles. Swap in skim for higher-fat milks as you learn how to froth milk. The chemical structure of skim milk is better at holding foam at room temperature. As a shortcut, you can use whatever type of milk you prefer for your drink and then spoon skim foam on top. Fill your carafe or another container (if your frother is electric rather than manual) so the milk only fills 1/3 of the volume. This will leave plenty of room for your milk to grow in size when you froth it. Place the carafe in the refrigerator to make the milk cold. This is especially important if you buy UHT milk, which is normally unrefrigerated. Dip a spoon into the milk after 30 minutes to test the temperature on your wrist. Remove the milk from the fridge when it is cold to the touch. You can froth steamed milk, but it will make less froth. It's best to froth the milk then heat it if you'd like your foam to be hot. There is not a particular temperature your milk needs to be chilled to.
Question: What is a summary of what this article is about?
Buy fresh milk. Use skim milk if you're new to frothing. Pour your milk into the carafe of your manual frother. Chill your carafe of milk.

Problem: Article: Keep your hands about 3in (7.6cm) over the person who has their eyes closed. Wiggle your fingers so it looks like you're "sensing their energy" so you can perform the trick. In reality, wiggling your fingers helps divert everyone's attention away from your actual movements. Don't touch the person who has their eyes closed by accident or else you may spoil the rest of your trick. With the elastic pulled tight, hold your hands on either side of the first person's face. Lightly move your hands downwards in front of the person's face and wiggle your fingers so the edge of the elastic band grazes the tip of their nose. Be sure to stay fluid and deliberate with your motion so it looks natural. At the end of your movement, make fists with your hands, but leave the elastic around your palm. Take a playing card out of your pocket and show it to your audience and the volunteers. Hold the edge of the playing card and slowly run it down the tip of the second person's nose. When you're finished, put the playing card back in your pocket. Lightly touch the end of the playing card against their nose so you don't accidentally give them a papercut. When you're finished, tell the person with their eyes closed to open them. Then, ask if the person felt anything while they had their eyes closed. When they say they felt someone touch them, ask them where they felt it. The person who had their eyes closed will say their nose because they felt the elastic. The audience can't see the elastic, so they'll think the person with their eyes closed felt something when you touched the second person's nose with the card. Make sure that you thank your volunteers for helping you before they sit back down.
Summary: Wave your hands around the person who has their eyes closed. Scrape the elastic over the tip of the person's nose. Touch the other participant's nose with a playing card. Ask the person who had their eyes closed if they felt anything.

Sit down comfortably with at least one foot flat against the floor. Your knee should be bent down at a 90 degree angle, making your leg perpendicular to the floor. You should also relax the muscles in your leg as you prepare to measure it. This leg is the leg you will need to measure. The vast majority of people can get away with only measuring one leg, but if one of your legs is slightly shorter than the others, you may want to consider measuring each leg separately. Your leg is straightest in this position which is why you need to keep it this way for both your calf height and circumference measurements. Place the end of a soft tape measure at the bottom of your heel. Extend the tape measure upwards, over the back of your leg, until it hits a point just below your kneecap. You can then take this calf height measurement and compare it to the shaft height measurement of the boots you are looking at. Find the measured height of the boot on the tape measure as you have it pressed against your calf. This spot is the point at which the boot shaft will most likely land on your leg. Locate the widest part of your calf and place the end of a flexible tape measure there. Wrap the tape measure all the way around your calf until it intersects with this starting point, then take the measurement at this point of intersection. If you want to be really precise, figure out where the top of the shaft will land on your calf using the shaft height measurement and measure the circumference of your calf at that point. Compare your calf measurement to the shaft circumference of the boot. If the boot shaft circumference is smaller than the circumference of your calf, the boot will not fit well. If it is an exact match, the boot will fit but may feel a little too tight or snug. If the shaft is too much largerusually 1.5 inches (3.8 cm) or morethe boot may end up feeling too loose. A boot shaft circumference can, however, be 0.5 inches (1.25 cm) smaller than your calf circumference if the material has enough elasticity to stretch over your calf. An ideal situation would be for your boot shaft circumference to be 0.25 to 1 inch (0.6 to 2.5 cm) wider than your calf circumference. Beyond the basics of fit, your ideal boot shaft height is merely a matter of personal taste and preference. There are a few things worth keeping in mind when considering how high you would like a boot shaft to be, though. If the shaft of a certain boot will end right at the crease of your knee, that boot is likely to pinch and rub your skin as you sit, making it uncomfortable. If you have notably wide calves, the best options will usually be ankle boots and similarly short boots. The shaft of these boots will stop just above your ankle and below the widest part of your calf, creating a more relaxed fit. Your height can also determine an ideal boot shaft height. As a general rule, shorter legs look better with shorter shafts and longer legs look better with taller shafts. If you are petite, a shaft height taller than 14 inches (35.6 cm) may overwhelm your figure. If you are tall, a shaft height shorter than 15 inches (38.1 cm) may throw off the visual balance of your legs.
