How to Make a 2 liter Bottle a Rocket ship

In this article you will learn how to easily and safely create a rocket ship out of a 2 liter bottle. Great for science teacher and parents alike

Instructions DIFFICULTY: Easy

Things You'll Need:

• 2 liter bottle, a little less than half full.
• A bicycle pump.
• Common wine cork
• optional, construction paper and any other materials used to customize and design "rocket"

Step 1

You will need to first make the 2-liter bottle stand on its own, upside-down. you can do this by using glue and cardboard to apply "legs" to the bottle. a tri-pod formation works best.

Step 2

You will then fill the bottle a little less than halfway with water. Apply the cork to seal out the water from escaping the bottle. Water temperature will not play much of a factor in this experiment.

Step 3

Outside in an open area, insert the needle from the bicycle pump into the cork at the base of the bottle and start pumping slowly. After about 5-7 pumps the air pressure will build and the cork will pop out. This will cause a "blast off" and if all goes well your "rocket" should launch about 30-60 feet in the air.

How to Create a WiFi Booster Antenna for PSP

If your PSP is experiencing problems connecting to the Internet through WiFi, you can make a quick and easy homemade WiFi booster antenna. This is much cheaper than purchasing the Sony antennas, and it works just as well, especially if you are only need to download updates to the software.

Instructions DIFFICULTY: Moderate

Things You'll Need:

• Pliers
• Copper wire (about a foot)
• Electrical tape

Step 1

Twist the copper wire into a small circle, about the diameter of the PSP logo on the back, or 1 1/2 inches. Twist the end into an inch long coil, double and tripping wrapping the wire so that it is about 1/8 inch thick.

Step 2

Tape the circle to the back of the PSP, using a small amount of electrical tape.

Step 3

Place the coiled end of the wire into the USB port on the bottom of the PSP. Secure it with a small piece of electrical tape. Note that this is completely safe and will not damage the USB port in any way since there is no current running through it. Furthermore, since the WiFi antenna is connected internally to the USB port, this is the only way to create a physical connection to the PSP's internal antenna without opening your handheld.

Step 4

Turn on the PSP. From the main menu, select SETTINGS then WiFi. Select Search, and you should receive a list of available connections.

Step 5

Check that the connection percentage, located on the right, is greater than 30 percent. If so, your antenna is working properly, and you now have greater WiFi range on your PSP.
