In one sentence, describe what the following article is about: You can buy a new stepladder, or you can use a ladder you have lying around. Measure the ladder and the place you plan to store your tree house. If you are using an old ladder, clean it thoroughly before bringing it into your home. You might want to paint your ladder a cheerful color. Add boxes. Lash or glue a box or two to some of the steps. Add a pillow. You may want to string up a sort of hammock between the sides of your ladder and put a pillow on it for your cat to sit. If your cat doesn't like rocking, fix a piece of wood or a platter between the rungs. Make sure your ladder is balanced. If your cat or cats are sitting on one side, your ladder should not fall over or collapse on them. Pick a bookcase you are not using, or buy a new one. If it is sturdy enough to stand on its own, you do not have to modify it much. Otherwise, use furniture straps to tie it to the wall. Cut holes in each shelf large enough for your cat to slink through. Cut carpet squares to fit each shelf, and fix them in place with glue, nails, or staples. Buy a low-pile carpet to discourage your cats from chewing it. Cut the carpet into squares or rectangles to fit the shelves. Sturdy shelves can be fixed to your walls in "steps" or zig-zags for your cats to climb. Measure your cat's reach and leave the right amount of space for your cat to get from shelf to shelf. Attach cloth or carpet squares to the shelves so your cats can get a grip on them. Add a pillow to one or two of the shelves for cat comfort. Glue, nail, or staple everything you are putting on the shelves, as your cat may knock them off otherwise.
Summary: Build a stepladder cat tree. Convert a bookcase. Buy wall shelves for your cats.

In one sentence, describe what the following article is about: Monitoring moon phases is not as accurate of a way to keep time as making a sundial or measuring by the North Star. Based on the current lunar phase, the moon will only be visible in the night sky for a certain amount of time and it will be easiest to see when it is full or almost full. For example, during a full moon, the moon will be visible in the sky all night (for approximately 12 hours). The moon will be harder to spot throughout the night when it is not full. Knowing when the sun set will give you a baseline time to start tracking the time with the moon since the moon rises about 1 hour after the sun sets. If you can, look up the time that the sun set before you observe the moon's position and add 1 hour to this time to create a baseline time. For example, if the sun set at 6:30 pm, and the moon is just now visible on the horizon, then it is approximately 7:30 pm. You can use the moon to tell time by dividing the sky into quarters and noting the moon's position in the sky. Find the middle of the sky, and then divide these 2 halves in half to divide the sky into quarters going from east to west. This won't give you an accurate time, but you can get a good estimate. Look at the moon's position in the sky in relation to where it rose. For example, if the moon is of the way across the sky from where it rose, then it is about 3 hours past sundown. If the moon is halfway across the sky, then it is approximately 6 hours past sundown. If the moon is of the way across the sky, then it is 9 hours past sundown. The location of the moon in the sky along with the time the sun set, will allow you to calculate an approximate time. Once you have noted these details, add the number of hours for the position of the moon to the time of sunset. For example, if the sun set at 7:00 pm, and the moon in halfway across the sky, then the approximate time is 1:00 am. If the sun set at 6:15 pm, and the moon is of the way across the sky, then the approximate time is 3:15 am.
Summary: Use the moon to tell time only when it is at its brightest. Find out what time the sun set. Track the position of the moon to determine the approximate time. Use the moon's position to calculate the approximate time.

In one sentence, describe what the following article is about: Buy skull molds with a front and back section from mexicansugarskull.com or a similar online store. Buy skull molds with a front-side only from Amazon.com. You can buy molds in small, medium and large sizes. This is a traditional baking ingredient used to hold together sugary frosting. CK Products, Wilton and Ateco make high quality meringue powder. This product costs about $7 for 4 oz. For large batches of sugar skulls, you will want to buy several containers. Most traditional Day of the Dead recipes say that the skulls will not form properly on a rainy day. Use 4 cups (800g) of sugar, 4 tsp. (13.3g) of meringue powder and 10 tsp. (49ml) of water. You may add 2 extra tsp. (10ml) of water later. If you are making a large batch of sugar skulls, use 10 lbs. (4.5kg) of sugar, 1/2 cup (80g) of meringue powder and 7 tbsp. (104ml) of water. If you want to make colored sugar skulls, mix food color with the water before pouring it into the bowl. Make sure you continuously incorporate the water at the bottom of the bowl with the sugar at the top, since the water will settle to the bottom. Add 2 tsp. (10ml) of water if the sugar isn't sticking together. If you press the sugar together with your hands and your fingerprints imprint and stay, it is ready to mold. If the sugar falls apart or fails to imprint, there isn't enough water in your mixture. Pack it very tightly. Smooth the back of the mold with a straight edge. Leave 12 inch (1.3cm) of sugar on all sides. Do not scoop out the neck portion, or it will be too fragile. You must remove this section to ensure the skull will dry quickly and evenly. They should take approximately 8 hours to dry. Pour 1/2 cup (40g) meringue powder with 1 cup (237ml) of water. Mix well with a hand mixer. Add a 2 lb. (0.5kg) bag of powdered sugar to the mixture. Stick the back and front of the skull together to dry. Allow them to dry for 4 to 8 hours before decorating. Pour in drops of food coloring and mix well. Decorate your skulls with colored royal icing.
Summary:
Purchase your sugar skull mold. Buy a large container of white granulated sugar. Order merengue powder. Wait for a low-humidity day. Measure your ingredients and place them in a large bowl. Mix together your skull recipe with your hands. Test the sugar. Pack sugar into the front and back molds with your hands. Scoop out the center of the skull with a spoon. Set the molds with sugar side up to dry overnight. Flip out the skulls onto a piece of cardboard. Make your royal icing. Put a layer of white royal icing on the back of each side of the skull mold. Separate royal icing into bowls.
