Hi all


At last PSLE over for DS. Just want to share his answer for the qn where you are in the forest, given newspaper, towel , plastic sheet and string. How to get water when you are thirsty? I don’t know if it is acceptable. Science tutors or teachers please give your comments. I have a good laugh. He said that his P5 Science teacher have taught him this method of getting pure water.
I feel very high tide. I urinated on the towels. Use the string to tie on both ends of plastic sheet and then tie both ends to the trees. Place the towels under the plastic sheets. The urine evaporated and water vapour condensed on the inner surface of the plastic sheet form water droplets. Collect the prue water and drink.
