A ping pong ball fell into a tight deep pipe ( eg. 30 cm long, buried in concrete pavement – having firm metal bottom), only 1 cm of the pipe is above the ground – so it can not be moved. The pipe was only a bit wider than the ball, so you can not use your hand. How would you take it out, with no damage?
here comes the winners of the Easy and Short problem
not so many but better than the Fontas one 
the first is -for the first time i think 
–

then
Mohamed Gawish
then
AlaaShaker
and
Tasniem Seliem
go and check their solutions here
we have a rectangular cake, where a square portion is cut of it
that square may not be in the exact center of the cake
how can you cut the cake into two equal halves with only one cut.
well,
i know that this one was tough
it needed some imagination and geometry
and no one had answered it except Alaa Shaker
go and check his answer
good luck with the next problems 
if you cant understand his solution we can explain it here, just ask 
A man has A Fontas (Uniform Cylinder) and infinite source of water, and a pencil.
He know that the volume of the fontas is 8 liters and he does not have any thing to calculate time , length or volume just a fontas , infinite source of water and pencil.
he want to divide the fontas into 8 equal parts (8 liters) and mark those parts of course using the pencil.
can you help him ?!
Well, it seem that the Feast have a special effect
Only TWO winners for this week ..
Metal_ then Tasniem Seliem
Happy Feast and the answer is as usual right here ..
One day, a frustrated Math teacher lost his patience with his students’ non-stop chatting. Thus, he decided to give the ultimate hard problem:
Find the only positive integer number less than 20,000 that is also a sum of three different positive integers, all containing exactly 7 factors.
There was a steady silence. Can you break the silence by figuring it out?
Last week results ..
The First one to solve was ..
Mohamed Gamal
then
Ibrahim Ahmed Mohammedy
then
