How to make a cloud in a  glass jar ?

Supplies:

                ►Large glass jar (one gallon size )

                ►Matches

                ►Rubber glove

                ►Rubber band

                ►Flashlight or a lamp

                ►Food coloring

                ►Water

How it work?

                   The air is full of warm water vapor molecules inside the jar. The air is compressed by the glove because the glove takes up some of the space inside the jar. Pulling the glove fingers out of the jar releases some space in the jar. The air inside the jar cools. The smoke from the match acts as a vehicle that the water molecules can attach to. They stick to the smoke particles, condensing into cloud droplets. When the glove fingers go back into the jar, the air inside the jar warms up again and the cloud disappears.

Step 1:      Pour boiling water into the jar.

               Cover to the bottom of the jar with water.

               Swirl the water around the jar.

               Use oven mitts if the jar is very hot.

Step 2:      Put the rubber glove wrist around the mouth of the jar.

               Having the fingers of the glove pointing downward into the jar will seal in the air into the jar.

Step 3:      Try to put you hand in the glove.

               With this you can make sure that noting happens to the water in the jar.

Step 4:      Light a match and drop it in the jar.

               Take off the glove from the jar for a moment.

               Light a match and drop it in to the jar.

               Stretch the glove back over the jar.

               The water at the bottom of the jar will put out the match, and smoke will from in te jar.

Step 5:      Light a match and drop it in the jar.

               Slide you hand into the glove and pull it outward agin.

               This time a cloud will form in the jar, and when you put you hand back inside the jar the cloud will disapper.

Step 6:      Have fun.

               If you use a flashlight on the jar you will be able to see the cloud better.

               If you add few drops of food coloring to the water in the botton of the jar, you can see the cloud bloom with differents colors.

               

Recycling

Recycling saves energy, reduce raw material extraction and combats climate change.

Other recycling facts:

• Every American makes about four (4) pounds of garbage daily.
• Every month Americans throw away enough glass bottles and jars to fill up a giant skyscraper (like the Empire State Building).
• Recycling one aluminum can saves enough energy to run a TV for three hours.
• Recycling one (1)-ton (approximately 2,000 pounds) of paper saves seventeen (17) trees, two (2) barrels of oil (enough to run the average car for 1,260 miles), 4,100 Kilowatts of energy (enough to power the average home for six (6) months) 3.2 Cubic-yards of landfill, and sixty (60) pounds of pollution.

Color classification of recycling

Blue – Paper

Green – Glass

Yellow – Metal

Red – Plastic

The recycling process

1.             Collection: In the first step of the recycling process, the recycling materials are collected.
2.       Processing: Once cleaned and sorted, the recyclables are processed to retrieve the raw materials, and the raw materials are then used in manufacturing recycled content products.
3.       Purchasing Recycled Products: The third step involves purchasing recycled products. This third step completes the recycling loop.

Exoskeleton

eLegs

The exoskeleton is a external skeleton that upports and protects the body. In nature we find diferents types of exoskeleton that are known as "shells", some examples are insects and crustaceans. The humans use that animal as idea to create the humans exoskeletons to help people with disabilities, the idea born as a military use, they think to use the exoskeleton to increase the soldiers capabilities, but people found a better use in medicine.

eLegs is a type of exoskeleton that support the legs of a pacient with disability, and help the paciento to walk. The suit consists of a backpack with a controller connected to a robotic legs . It is powered by four engines, two for the hip and one for each knee. The ankle joint is controlled by springs that keep the foot angled to walk . While the sensors in the legs send information to the control unit to determine how they should be bent joints. The team has lithium - cobalt batteries allow the suit to be operated with full autonomy .

How to test a LED bulb?

Before starting the  LED test we requieres a multimeter, thats is a1 special digital machine used to test the voltage of LED bulbs.

 First Step:   

                   Connecting the LED bulb to the multimeter.

            

The LED bulb has two terminals: the anode (positive) and the cathode (negative). Them you connect the black testing lead to the COM terminal on the multimeter and the red testing to the multimeter's terminal that ha the Omega sign. Be sure that black probe of the lead connect to the cathode and the red probe connects to the anode of the bulb. When you turn on the multimer display should show you "OL" or "OPEN".

Second Step:                     

                       Interpreting LED Test Results

If the multimeter display show you "OL" or "OPEN" you can be ure that connection is correctly, them you can start testing the LED bulb, first it is important to shield the bulb to see how it glows, if the bulb glows with a dim light the LED is with lower efficiency, but if the bulb glows with clarity and brightness the LED is with higher efficiency.

The Leaning Tower of Pisa

The height of the tower is 55.86 meters from the ground on the low side and 56.67 meters on the high side, the tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. The width of the walls at the base is 2.44 m .Its weight is estimated at 14,500 metric tons, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means that the top of the tower is displaced horizontally 3.9 meters from the center.
