In one sentence, describe what the following article is about: Place your lead foot near the front of the scooter behind the handlebar and position your back foot just in front of the rear wheel. Bend your knees slightly to get ready to spring up for the jump. Most right handed riders naturally assume what's known as a "regular" stance, with their left foot up front. If you're left-handed, you might be more comfortable standing "goofy," with your right foot up front instead. Getting your foot placement right will make your takeoff and your landing much easier. Use your arms to stabilize both the scooter and your own body. They'll also play a part in assisting the rotation of the deck (the part of the scooter you stand on), so it's important to keep them in place until you've completed the trick. Adjust your handlebars to the height that feels most natural to you. Stay loose and relaxed. If you hold on too tightly, it may make your arms rigid. This stiffness can easily spread to the rest of your body and impact your jump or timing. Try to build up to a moderate speed, about the same pace as a slow jog. After your last push, replace your back foot on the deck of your scooter and keep your eyes fixed in the direction you're riding. Going too slow may cause you to lose your balance, while going too fast will make it harder to control your movement. Make sure you're practicing somewhere where you have enough room to ride in a straight path for 1520 feet (4.66.1m). If you're not confident enough to try a tailwhip while in motion, you can perform your first few attempts from a stationary position. This will allow you to focus on your technique without having to worry about the ride up just yet. Later, you can work on putting the two phases of the trick together. One downside of throwing a tailwhip while standing in place is that you have to initiate the jump as soon as you get both of your feet on the scooter, which doesn't give you much time to set up.
Summary: Stand on the scooter in a comfortable stance. Grip the middle of the handlebars with both hands. Push off a few times with your back foot to get moving. Practice the tailwhip while standing still.

In one sentence, describe what the following article is about: These usually look like small pink circles and may appear slightly raised around the edges. The anus is just under the tail, and the urogenital opening, the location of the urinary and genital organs, is above the anus toward the center of the abdomen. Sex differences are more difficult to spot in very young pups, but it is possible to sex a pup by looking at the distance between its anus and its urogenital opening. In females, the openings are very close together. You may actually have trouble telling them apart so that the urogenital opening, which in this case is the vulva, and the anus almost seem to be a single opening or structure. In males, the openings are farther apart, so there is very clear separation between the anus and the urogenital opening. You may also see small swellings in the groin area if you have a male. These are the growing testicles. If you can only find one opening, especially if it seems rather large, you should suspect you are dealing with a female, but recheck the animal often or consult an experienced exotics veterinarian just in case you missed the second opening. This opening can be subtle in a very young male, especially if the animal you are working with is a tiny dwarf hamster. The most common pet hamsters, Syrian hamsters, are solitary and need to be kept in individual cages, so early sexing is not very important. Dwarf hamsters, on the other hand, are kept in single-sex groups. If you have pups in a single-sex group, you need to recheck them often until sex is obvious. This will help you avoid accidental pregnancies in your group.
Summary:
Locate the two openings on the underside of the hamster. Assess the distance between the anus and the urogenital opening. Recheck the hamster at another time if you are still not sure.
