My son came across this in a fiction book months back


1.\tDig a hole in the forest ground
2.\tMake a cup with the newspaper
3.\tTear the plastic sheet into two
4.\tLine the cup with the plastic sheet
5.\tPlace the cup into the hole
6.\tPlace the remaining plastic sheet over the hole and wait

(The sun will evaporate the water from the soil, and the water vapour will condense on the plastic sheet, and drip into the cup.)

Fact or fiction?? :roll:

fact. but dig with the hands? :?

I want to know ans for qns 34

It's about 'someone' is in a jungle,all the fruits and plants cant be eaten he only have the following items to produce drinkable water:
.Plastic Sheet
.Newspaper
.Towel
.String

What should he do?

Help me with this qns pls..... :idea:

I think my earlier answer is wrong. The towel and newspaper is to be used as filter. The answer may be in this link :

O, oh!

but to filter thru towel means lot of water needs to be collected. say 200 ml atleast. Other wise the towel would soak up most of the water.

newspaper if used as filter may just tear.

hmm...
