Smoke Goes Down !

Articles Required : An empty card­board shoe-box, two chimneys of kerosene lamp, can­dle, cigarette and matchstick. Whenever you burn something the smoke moves upwards. Isn't it? Now, how would you react if you're asked to make it go downwards? Will you be able to do it? Well, once you try the experiment explained below, you'd naturally quip after that "Oh, it was so easy!" Make two holes in your shoe-box as shown in the figure here and fix the chimneys in both of them. If you can't find such chimneys, you can use even the empty talcum powder tins after cutting their tops and bot­toms. Having done this, remove the shoe-box cover and put a burning candle just below the left chimney. Now replace the cover and paste cello-tape on the joint of box and its cover to restrict air entry from the slit. Now, if you light a cigarette and bring it on top of the second chim­ney, something interesting would happen. The cigarette smoke, instead of going upwar...

Make a Rocket

Rockets are fascinating!  They soar into the sky and help us know many secrets. Are you fascinated by rockets? If your answer is yes, you would be interested in this activity. The rockets that you can make safely will not go very far, perhaps much less then the rockets we enjoy on the Deepawali day. But then you will agree, the fun and excitement to make your own rocket has a totally different dimension.  The basic principle of rocketry is Newton's Third Law of Motion, that is, "For every action there is an equal an opposite reaction".  A big rocket uses chemicals to release an intense stream of gas out its tail end that propels it upwards.  A fuel is used in a rocket to produce this gas through some chemical reaction. The rocket fuel is sometimes liquid, and sometimes solid.  But, in all cases, a gas is ejected from the tail of the rocket. The first kind of rocket that we can make is propelled by a very safe gas - carbon dioxide.  The ...

Make a Periscope

Are you familiar with the word "submarine"? A submarine is a kind of boat that moves underwater. Submarines are common crafts for the Naval forces of any country. But, while moving underwater, submarines need to know where they are with respect to other objects on the surface of water. The device they use to do this is called a periscope.  Periscopes are optical instruments that can afford submariners a limited though vital visual picture outside their windowless hull. Traditionally, periscopes offered the submerged submarine its only glimpse of the outside world. Classic English war movies have also made them the submarine's most familiar feature.  For most of us, who are unlikely to come across submarines in real life, a periscope can make it possible to see round corners and over the heads of crowds during processions or at sporting occasions. In a periscope, two mirrors are arranged at 45 degrees to each other. One mirror captures the rays of light from t...
