context: How to use a pay phone
Carry enough coins for a phone call.
Some pay phones-especially those in airports and train stations-also accept credit cards these days, but the charges for those can be extra high. Make sure you read the cost on the machine before paying.

OPTIONS:
- Some phones may charge towards the recipient's money card. Consider leaving one free jack on your service phone.
- Know your minimum phone charges when charging. If you plan to call in cash, find out what the minimum number (4 , 100 canadian pounds) is to call instead of what is included for a credit card (7 , 200 us dollars).
- If you are planning to make calls in the bathroom, remember to bring coins (around 20 euros worth). For emergencies, you might want to use a us post card or traveler's check instead of a credit card to receive you more coins.
- Buy a small pack of wet wipes and gently wipe over the phone. You don't know who has used it before you.

context: How to survive a tsunami (for kids )
Determine how at risk your home is.
During a tsunami, low-lying areas near the ocean are extremely vulnerable to the waves. You should know how at risk your family is before a disaster occurs, so you know how to prepare.

OPTIONS:
- Decide how you will respond to a tsunami. Are you out of your house for a disaster of this magnitude? Did you see a tsunami? Was it the first time you saw a tsunami? Are you surrounded by a tsunami? Prepare for waves.
- You should make certain your family is at risk before a tsunami-or even a full-blown tsunami. Stay in the safe areas in your home.
- Your parents will probably know if your home is a tsunami hazard area, but you should also know how high your street is above sea level and how far your neighborhood is from the coast and other areas where waves may occur. Those numbers usually help officials decide if you need to evacuate during a tsunami.
- Consider how you can help a local body of water or to save a nearby one when the tsunami arrives. Use these circumstances to decide if you and your family can survive.

context: How to create an iphone app demo
Make up your mind about the scenario you want to demo.
One of the best selling scenario is showing your potential users how your app solves one of their problems.
Take screenshots of this scenario, screen by screen.

OPTIONS:
- Use the camera your app is installing to take screenshots. You can even make the camera a " tile vision " of the app.
- Using photoshop, images are transferred from one screen to another, displaying their scripts and colors in one display. Have a customized screenshot in the app settings window.
- If there is a problem or a way to fix it, that's great. If it's something you can fix, then you're done.
- When you are on a screen that you want to capture, press and hold the home button and then press the power/sleep button. Your screenshots will then appear in your photo gallery on your iphone/ipad.

context: How to stop cracking your knuckles
Understand what causes the cracking sound.
When you crack your knuckles, you are manipulating certain joints in the body in a manner that promotes the release of gas (currently thought to be primarily nitrogen) from synovial fluid. Synovial fluid exists within synovial joints, and its function is to reduce friction between cartilage.

OPTIONS:
- When a knuckle is cracked, the gases dissolved within the synovial fluid are compressed and form of a bubble. This bubble then bursts, making that familiar popping sound as it does so.
- This friction is a result of the formation of dialogal cell walls. Learning how to break these spacial and internal tissues can help you prevent cracking your knuckles, which can cause swelling.
- A lingering gas behind your joints may actually be caused by the spreading of the fluorocarbon builds up inside of these joints. For example, a building might have one joint that was once home to a high density steel building.
- This is the reason that cracking knuckles is so important, for persons with weakened gums. This occurs due to the inferior receptors in the joints.
