How to create your own theodolite from home?

It is very much interesting to observe distant objects,it is more
important to remember where and how to see it later.so we have to know
its location.we cannot tell about a star,like near my house or my
school etc..a little knowledge of trigonometry ad geometry can make us
master in it.
Here iam going to discuss about creating a THEODOLITE which has a
major use among sky observers,in astronoimy to locate and mark the
position of celestial bodies.so the construction begins: needed objects:
1.2cd's
2.one 50 cm pipe
3.color pens,pencils,markers
4.cardboard
5.small stick
6.drawing pins/safety pins

Lets work on it.1st take the 2 disks and with the help of a
protractor/pro circle mark 0-360 degrees on both Cd's,better try to be
maximum accurate.use appropriate pen or pencil or marker,we need not
want the markings to erase,means use a permanent marker.now take a
small sheet of card board or wood,place one of the disk's on it and
glue it firmly.now place a stick on the center of disk which can
rotate,glue it wisely.now attach the 2nd disk laterally,perpendicular
to the 1st disk,on the stick.(better to pin it using a nail
pin),extend the pin through the center of the 2nd disk.attach the
small pipe to its end,so that it too rotates.The theodolite is ready.
I had explained in the most condensed way,easily for each youngsters
can understand,but may lack many things.
remember,once you got the idea,modify the instrument with the way you
want.(for example: creating a stand for the apparatus,replacing the 50 cm small pipe with a telescope etc...)
marking of North,East,West and south will make your observations more
easier to mark and study,a permanent space to install the apparatus in
your room or near the windows or upstairs would help you for a long term research.

Smoke by hands...!?

Most of the guys have a tendency to amaze and make your friends or classmates thrilling. Here i.e. a new trick for that. This is not silly math’s trick or complex calculations to detect the future. It’s a pure bit of chemistry. It’s safe and you do not have any expenses. Let me explain the thing:

First you have to collect some match boxes, which has been already used. You could get it from every inch of place as now it’s an era of smokers. Collect as many as matchboxes. Now use a blade or a knife and scrap the side of matchbox. There will a fine coating of phosphorus like material used to lighten the match stick. You have to scrap them as slowly as possible and as lightly as possible. You must take care not to include and scratching of the paper or other parts of match box. You must get the pure brown coloured powder. Collect at least 5gm of it, to show the trick for one time. Now take that scratched powder, keep it in a small steel box(or any other less reactive metal boxes-try to make the size of box as less as possible, better is to use a size similar to a matchbox) and burn that powder somehow using your own method, you will obtain a yellowish oil, like coconut or almond oil. Save this oil in the same steel box.donot open the box to air for too much time.

Now it’s time for the show. Just scratch some oil with your finger from the box (not too much), you must do it as you touch the pickle during lunch. And now with the oily finger, just rub your fingers gently.wow, you would see the magic. Lot of fumes and smoke will be coming from your hand. There won’t be any fire or pain but still a lot of smoke. This can be performed by you in your own ways and methods. The more the pure is brown powder the more is the amount of smoke and the more your item works.
