This will teach your fish that seeing your hand means that they will be getting fed. Make this a normal routine so that your fish becomes familiar with your hand, and knows what to expect when it comes time for feeding. This will also help your fish begin to develop trust with you. Start by getting your fish's attention by placing your fingertips in the water. This should get them to swim to the surface. If this does not get their attention, hold some food in your fingertips as you place them in the water. Do not release the food into the water, as you should not feed them until they have performed the trick. After you've gotten their attention, dangle some of their food just above the water. If your fish does not jump for the food right away, you'll need to encourage them. Place your fingertips full of food on the surface of the water, and pull them from the water as your fish approaches. This should encourage your fish to jump from the water to eat their food. This positive reinforcement will show them that jumping from the water will get them an extra treat, as opposed to just their regular food.

One-sentence summary -- Feed your fish by hand every day. Train your fish to swim to the surface for feeding. Hold your fish's food just above the water. Reward your fish with some treats once they jump out of the water.

Article: Use pruning shears for thinner branches and a fine-toothed pruning saw for thicker ones. Leave about 3 to 5 shoots per branch.  Finish cutting on an outward-facing shoot. This way, the new branch will grow outward, not inward. Leave the outward-growing branches and prune off the inward-growing ones. This will help increase air and light circulation. Summertime is the best time to remove the suckers, but if your plant is producing a lot of them, you will need to repeat the process more often. Once in the late spring and once in the early fall is a good rule of thumb.  Use the same method as you did before to remove the suckers and water sprouts. Don't let these grow and develop. They'll just suck up the water and nutrients that could otherwise go to your tree. Once your tree enters its third year, it is well-established and doesn't need as much heavy pruning. A light prune in the late winter after all danger of frost has passed is all you need.  Keep up with the suckers and remove them as you see them. Cut the dead or diseased branches a few inches/centimeters below the diseased portion. The exposed wood should look healthy.
Question: What is a summary of what this article is about?
Cut the branches back by about a third. Remove suckers and water sprouts at least once per year. Remove dead or damaged branches starting from the third winter.

Article: Visit your local library or a bookstore to begin reading about electronics. Even older books have a lot of information about electrical circuits and how they work. Use it to study the basics before you begin building your own circuits.  Try books like Make:  Electronics, The Art Of Electronics, or Foundations of Analog and Digital Electronic Circuits. For more resources, search online for informative websites and digital book copies. Search your phone’s Play Store to find a number of informative, hands-on apps. Some apps teach you the basics of electronics, while others let you design your own circuit board using a touchscreen. For example, try Electronics Basics or ElectroDroid. An electrical current consists of electrons, which are the negatively charged particles in atoms. In a current, the electrons flow from a negative source, such as a battery terminal. Then, it flows around the circuit and returns to the positive terminal. You can think of it like a faucet. When the faucet turns on, “water” is pushed through until it reaches the end of the pipe. Voltage is a measurement of the force needed to make a current flow through a circuit. In a circuit, the electrons accumulate near the battery’s negative terminal. Energy is needed to get the current to flow through the circuit, and this measurement is the voltage. Think of it as pressure in a water tank. When water is drained from the tank, the pressure goes down and less water flows out. Resistance slows the current in a circuit. Different materials inhibit electricity more than others. You will need a stronger electrical current to pass through insulation than a conductive material like metal. This increases the voltage. For example, imagine water pipes of different sizes. Water faces more resistance flowing through the smaller pipe due to the lack of space. Electrical diagrams and schematics use symbols to denote components. Before you can copy one to build your own circuit, find out what the symbols mean. Search online for a list of symbols used as shorthand in diagrams.  The straight lines are wires. A battery is represented by a + sign followed by a long and short straight line. Diodes, for example, are represented by triangles. Resistors are represented by squares or jagged lines.
Question: What is a summary of what this article is about?
Read books to learn the fundamentals of electronics. Download a phone application to study electrical engineering. Study how a current travels along a wire. Read about the voltage in a circuit. Study the resistance factor of different objects. Read circuit diagrams to understand the notation.
