Answer: A good cage for your hamster is one that keeps him safe and is easy for you to clean.  A wire hamster cage with solid flooring is generally the best choice.  The bar spacing in a wire cage should be less than one-half inch to prevent him from escaping. The wires should also be covered with a substance called PVC to prevent rusting. Make sure the cage flooring is smooth. Your dwarf hamster could get his feet stuck in wire flooring and possibly break one of his leg bones. If you have a cage with wire flooring, cover the flooring with a smooth material, such as cardboard or laminate flooring (available at a hardware store). Cages with colorful plastic tubes and tunnels are fun to look at, but can be very difficult to clean. In addition, your dwarf hamster could chew through the plastic. Clean your hamster’s cage and its components once a week with hot water. His bedding should also be replaced with each cleaning. Glass aquariums do not always circulate fresh air very well, which could lead to a high level of ammonia in the cage, which can be toxic to your hamster. Clean the aquarium regularly to prevent an ammonia buildup. Glass aquariums also lack good ventilation and may heat up rapidly if placed in direct sunlight. The fact that your Russian dwarf hamster is small doesn’t mean you should put him in a small cage. In fact, the larger the cage, the better. Your dwarf hamster’s cage should be at least 60 cm (24 inches) long and 40 cm (16 inches) deep.  A larger cage will not get dirty as quickly. With a large cage to call home, your dwarf hamster won't be as likely to get bored or agitated. When your dwarf hamster is happy, he's less likely to develop compulsive behaviors, such as bar chewing, that are bad for him. If you have more than one dwarf hamster in the same cage, a large cage will keep them from being aggressive towards each other. If you have chosen a glass aquarium to house your dwarf hamster, it should be at least 10 gallons. Cage bedding has several benefits. It helps keep the cage clean by soaking up your hamster’s urine. Cage bedding also helps your hamster feel more at home. He'll be able to forage and burrow as much as he likes.  Pine shavings would be a very comfortable bedding for your hamster.   Do not use cedar bedding. Cedar oil can cause your hamster’s fuzz to fall out and his skin to crack. If his skin cracks, he can become dehydrated and very sick. Place your hamster’s cage in a comfortable room (65 to 75 °Fahrenheit/18 to 24 °Celsius) where the temperature stays constant and there are no drafts. Within the room, do not place the cage near a heat source (e.g, fireplace, window with lots of sunlight) — this could warm up the cage too much, especially if it is a glass aquarium.  A room that is too cold (below 60 °Fahrenheit/15 °Celsius) could make your hamster very sluggish, possibly to the point of hibernation. Because hamsters like to play at night, your bedroom would not be a good place for your hamster’s cage. The noise of his activity could keep you from getting a good night’s sleep.


Problem: Write an article based on this summary: Create the frames for your walls and nail them in. Lay 4 joists in between the 2 vertical sides of your wall. Raise your 4 walls up and nail them in at the corners and bottom of your frame. Install the sheeting for your walls on the exterior and interior of your playhouse.

Answer: Measure out the length of your first wall with a measuring tape so that it matches the joists that form the long side of the floor. Calculate the height of your wall based on the height of your taller porch posts. Lay the 4 exterior sides of your first wall out on the ground by placing 4 joists in a rectangle with your floor-length section laid parallel to the ceiling. You can use joists of the same size as the joists in your floor. You can also use 2 in × 4 in (5.1 cm × 10.2 cm), 4 in × 4 in (10 cm × 10 cm), or 4 in × 6 in (10 cm × 15 cm) joists if you’d like. With your rectangular frame laid out on the floor, spread 4 joists out in the middle so that they are parallel and equidistant from the other joists on the ground. Push each piece together so that their flat edges are flush with the exterior joists of your wall. Nail each interior joist to its exterior side with a nail gun. Repeat this process for all 4 walls, leaving the section across from your shorter porch posts empty for a door.  While holding the edge of your interior joist flush against the edge, fire your nail gun at a 45-degree angle through the interior joist towards the exterior edge. Do this on both sides to secure it. The distance between your joists will change based on how big you’re making your playhouse, but don't space them more than 24 inches (61 cm) apart. Hoist each of your 4 walls on top of the platform for your frame. Use a level to make sure that each wall is standing straight before you nail the bottom joist into the floor frame with your nail gun. Nail the 4 walls together in the corners and sides of the 2 joists where the walls meet with a nail gun positioned at a 45-degree angle between each edge. Use plywood or sheets of particle board and fit them across the body of your frame on the outside and inside. Fit each sheet so that it’s flush against each corner and edge. Nail each sheet into the joists that it’s covering with a nail gun by firing it directly into the joists at a 90-degree angle.  Wear gloves when handling large sections of plywood or particle board. If your sheets don’t fit perfectly across each wall and section of roof, you’ll need to cut a section with a jigsaw or circular saw to fill in smaller openings. If you do, install your pieces vertically to prevent putting too much pressure on each piece.


Problem: Write an article based on this summary: Hold the ball flat in the palm of your hand. Keep the ball above the table and behind your serve line. Keep your racket hand below the table to hide it. Throw the ball at least 6.3 inches (16 cm) up in the air. Strike the ball when it’s falling. Bounce the ball on your side before it goes over the net. Hit anywhere on the table if you’re playing singles. Hit the opposite diagonal if you’re playing doubles. Move your free arm away from the ball once you’ve served.

Answer:
To start a legal serve, keep your hand completely open and flat after you pick up the ball. Let the ball sit there for a second or two, as your hand needs to be stationary, or still, before you throw it up into the air. Any illegal serve can result in the official calling it “incorrect.” While you may be warned one time during a match or if the official is unsure if the serve is legal, any clearly incorrect serves will lead your opponent to get your points! The hand holding the ball (which will become your “free hand”) has to be above the table as you get ready to serve. The ball itself should remain behind the end of the table (your serve line). Your thumb can cross the serve line as long as the ball itself doesn’t. Unlike the ball, your racket can be hidden under the table. Doing this may help you hide the kind of serve you’re going to make. You’ll need to quickly bring your racket up once you throw the ball into the air to get ready to serve. Until you’ve practiced serving, leave your racket hand above the table. This tricky technique is legal, but it’s best reserved for more advanced players. This is the minimum height required by the officials. Any lower and it won’t be counted as a legal serve. The ball needs to be thrown up vertically rather than sideways or diagonally.  Make sure that your throw makes the ball go almost straight up into the air. You can’t, for example, just drop the ball from a height of 6.3 inches (16 cm). This won’t be considered a vertical toss. Don’t hit the ball when it’s still going up in the air or when it’s at the top of your throw. Wait until it’s coming back down toward the table to avoid getting called out by the official. Hit the ball so that it lands on your side first. If it just sails over the net without bouncing, it’s an illegal serve.  Practice until you get the proper amount of force needed to follow this rule. You want a serve that’s fast enough to trick your opponent, but not so strong that it misses your side of the table. The ball can also go around the net so long as you can curve it enough to get it back onto your opponent’s side of the table. This is a pretty difficult skill, so aim straight over the net until you’re sure you can make a curving serve. Your opponent’s whole side is fair game if it’s just the two of you. This lets you really use the table. You can do short and long serves to make the match more difficult for your opponent. You’re restricted to the square that’s diagonal from you if you’re playing with partners. Anything that hits outside this square is illegal. It’s illegal to “hide” the the ball from the official or your opponent with your hand once you’ve served. Pull your free hand all the way back so you don’t get accused of doing this.
