In one sentence, describe what the following article is about: To ensure you build the best and safest catapult, find durable and strong materials to withstand the extreme forces your catapult will use when shooting objects. There are a great many materials you could use in the construction of your catapult, but at minimum you will need:  Broomstick or crank Padding Plywood (1/4" to 1/2" thick, 15" by 18 and 1/2") Rope (strong, stretchy preferred,like kernmantle rope) Screws or bolts Weights (optional) Wood (preferably non-flexible, like oak wood) If using 2x4 planks collect: two pieces at 36", one piece at 30", four pieces at 15", and one piece at 18" Since your catapult utilizes such powerful forces to eject its payload, you will need a strong and sturdy platform for launching as well as a strong and stable foundation. Poor foundation can throw off your aim or cause your catapult to fail. Torsion catapults, which is the technical name for a normal catapult, have historically been built with heavy, reinforced sides, as these would allow for heavier payload, greater tensile force, and greater stability. For the base of this catapult, you will use a 2x4 base supported with plywood triangles. To prepare your plywood supports, take one rectangular piece of plywood 1/4" to 1/2" thick, 15" by 18 and 1/2", and cut it diagonally into two equal triangles. Traditionally, spruce or fir wood were used for the throwing arm, as these woods were light and strong. Consult your local lumberyard to see if these are an affordable option and, if not, ask for some alternatives, two of which follow:  Thick PVC pipe Metal pipe (lightweight, durable) You will need rope torsion to provide the launching force for your catapult. The more twists, the greater the torque, the more power your catapult will have. The amount of torsion (twisting) you can achieve is limited only by your strength and the strength of the materials you've used in making your catapult. To make your torsion handles, take a broomstick and cut into two 15 inch segments.
Summary: Gather the materials. Contemplate base and weights. Cut your plywood supports. Choose the right material for your throwing arm. Cut your torsion handles.

Whether you're using a tall glass or a classic metal cup, popping it in the freezer for a few minutes will keep your milkshake frosty as you sip it. There's no need to stand around – get started on the milkshake while you wait. Using ice cream straight from the freezer can make your milkshake taste dilute, thin, or icy. You'll have much better results if you leave the ice cream out on the counter for about ten minutes, until it's soft and just beginning to melt around the edges.  On a hot day, put the ice cream in the refrigerator for about 30 minutes instead. Heating the ice cream too fast can ruin the texture. This gentle method is best. Skip this step if using frozen yogurt.

One-sentence summary -- Stick a tall glass in the freezer (optional). Let the ice cream soften.

Q: Try to get home as soon as you can so you have more time later to hang out with your friends. Make sure the place is comfortable enough to work at, but not so comfortable that you will fall asleep. Make sure it isn't really cold, and get comfortable in a big sweatshirt, but make sure it isn't really hot because that can make you really tired. Studies have shown that if you listen to music, you can increase productivity. Just make sure it doesn't drive you away from the work. Also, keep some "brain food" nearby, like fruits, vegetables, or maybe a sandwich. Just don't use anything messy! Look in your agenda and see what you have to do. Example: in math, you have to do page 537, numbers 2-28. So instead of putting it off, just do it! That's only 27 problems! Even if you have several days to do your homework, do a little each day! Let's say for the same example above, you have three days to complete it. Rather than doing it all in one night, why not just do ten a day? When you're done with all your homework, then you can call your friends, play video games, do chores; the possibilities are endless. Just remember to put your outfit out before you go to bed at night.
A: Go straight home. Sit in a quiet place, free of distractions. Play some music softly. Take out your homework. Make homework a daily habit. Enjoy the rest of your day.

Next, wash your mustache with shampoo. This will remove the wax and skin oils from your mustache.  Some people choose to wash their mustache in the mornings. If you sleep with wax in your mustache, it may leave a colorful residue on your pillowcase. If shampoo isn't powerful enough to remove the wax from your mustache use dish soap instead. Your mustache can pick up all sorts of things throughout the day. Right before you have a meal, spread a small amount of mustache wax on the bottom strands of hair. This will help them stay clear of your mouth and insulate them from liquids.  When eating crumbly foods, wipe your mouth often to keep your mustache free of crumbs.

Wash your mustache daily. Be careful when eating or drinking. Eat foods that might help your hair grow quickly.

Problem: Article: Find a spacious, out of the way area and clean it off first. Lay your item flat. Keep the curling side facedown. Typically maps and posters are rolled so they curl inwards and over the image. That’s the side that should be facedown. Any heavy object you have around your home is useful here. Books are always a good choice since they distribute weight evenly over a decent amount of space. Get as many as you can to cover the map or poster. Remember to make sure the objects are clean before you place them. It’ll take some time for the weight to be effective. Curling can take a day or more to correct. You’ll have to keep your map or poster in a safe spot as you weight. If you tried rolling the item previously, the curling may be fixed within a couple of hours. With any luck, the item won’t try to wrap itself into a tube again. You can safely hang your favorite heartthrob on your wall. Some maps and poster will need longer, so repeat treatment as much as needed.
Summary:
Lay the map or poster flat. Weigh down the map or poster to flatten it further. Leave the weights alone for a couple of hours. Remove the weights and check your map or poster.
