article: Letting air out of your ocarina through points other than the sound hole will affect the pitch of the whistle. A controlled way to do this is to lift the four fingers on your right hand up and down, mimicking the motions a flute player would make. Lift a maximum of two fingers at once — the more ways there are for air to escape, the harder it is to get pitches. Note that this is difficult to do without causing your whistle to turn into an undesirable "rushing air" noise. You'll need to keep a good seal between your hands, lift your finger only slightly, and support the note with plenty of air. It can take as long to learn how to do this as it takes to learn how to make the whistle in the first place. The pitch you hear when you get a whistle out of a hand ocarina is the air between your hands vibrating. Creating a bigger or smaller space by changing the shape of your hands will let more or less air in, affecting the pitch. Just be careful to keep a tight seal between your hands so air can't leak out.  Making a bigger space (moving your hands apart) will produce a lower-pitched sound. Making a smaller space (moving your hands together) will produce a higher-pitched sound. Changing the way you blow can also change the pitch of the note your ocarina makes. Try making a smaller "o" with your lips for a higher pitch or a larger "o" for a lower pitch. Experienced harmonica players use a technique called a "draw bend" to change notes' pitches. You can get a similar effect by pulling your tongue to the back of your mouth as you blow to "bend" the tone of your note downwards. This takes practice!

article: If possible, always park beneath a tree, in the shadow of a building, or in another cool location.  If you’re parking in a structure, try to stay off the top level (which is not protected by a roof). Sun shades are foldable covers for your windshield.  To use the sun shade, press it against the inside of your windshield.  Open your sun visors to secure the sun shade in place.  The best sun shades will be coated with reflective chrome to deflect the sun’s rays away from your vehicle. Some sun shades have small suction cups in their corners to allow them to better attach to your windshield.  This type can also be used on door windows. Place them in whichever window(s) are facing the sunshine (you may want to park with the front of the car facing the Sun, to use a sun shade there). More than one can be used, but not on the door you need to open to exit the car. Fold the visors down to hold the front sun shade in place better, and to reflect any light that passes over the top. Beware that sun shades can easily blow in the driver's face or out the window once the car is moving, with the windows down. Fold them up and place a heavy object on top, such as shoes, or hold them in your lap, to prevent this. Cracking the windows a bit can allow air to continue moving through the car, thereby preventing your car from heating much beyond the outside temperature.  The more cracked windows the better (one inch / two and a half centimeters each), especially if you can create a cross-draft.  Don’t crack your windows if you’re expecting rain. One risk is that the door locks could be reached by a thief using a coat hanger or other tool, so beware of this. If you have dark brown or black seats, your car will absorb more heat than will a car that has light or brightly colored seats.  To remedy this, invest in some white or light-colored seat covers. Seat covers are easy to slip over your seats.  Like a bed skirt, they remain secure with built-in elastic bands around their perimeters.
