Stealth Technology

     

      Radar was a new and deadly enemy that discovered by USA for intercepting Soviet's aircraft on World War II . Therefore, Soviet think to make an invisible aircraft. Then Soviet had make an invisible aircraft, that invisbile aircraft can be seen by our own eyes BUT that aircraft is invisible for radar to detect it!

You guys might wonder how to make that 'invisible' aircraft. Well, actually that 'invisible' wasn't the type of name for the aircraft. Actually the name is 'stealth', yes it was stealth. Stealth plane or sort of stealth aircraft can't been detected by any types of radar and even any angle of it.

    Hmm... Sounds interesting huh? Well, let us discuss about how it works. The first thing I want to says about the stealth aircraft is the radar cross section is really-really small compared to normall aircraft and even compared to a Church bird. Stealth aircraft have potential to absorb most of the radar waves, so that the waves doesn't bounce back to the radar. Steath aircraft was design perfectly to absorb most of the radar waves. If you feels confused, grab a nearest paper and look it from the edge of the paper, that is how stealth technology works!

New! Weekly scienceperimentz

       artificial reverse osmosis

Reverse osmosis is a technic to purify water until molecule level.

So in this scienceperimentz
We will try to clean water until pure level

Material :

1.glass bottle (2)
2. Big plastic ware(1)
3.pipette (as many as possible )
4.sand( as many as possible)
5.rocks(as many as possible)
6.small rocks ( as many as possible)
7.pebbles ( as many as possible)
8.thumb tack

Procedure:

1.fill in the sand then pebbles then sand then small rocks then sand then rocks into the plastic ware .

2.made a. Very small hole on the plastic ware with the thumb tack then place the bottle directly underneath the hole and pour in dirty water into the plastic ware .

3.when the glass bottle is full proceed by reputting the water in the bottle into the plasticware .do this 6 times.

4.take the bottle and put some pipette on the bottle mouth and to hold the pipette still cover the bottle mouth with some playing dough until the pipette is attaching strong on the dough.

5. Connect the pipette to the second bottle and repeat step 4

6.boil the glass bottle filled with water and wait until all water has condensed .redo this until all 3 times .

7.water is ready to drink!!

8.if you fail please redo from step 1

Tesla coil

tesla coil is an coil invented by Nikola Tesla that flowsout high voltage but low current AC electricity.This coil allows electricity to flow without wire.This coil is can be very dangerus if we make it flow more than 220 volt electricity.
