Carry the water with condom!

You can find condoms in every bathroom in UN offices here!

This is what I learned from the security training! I am taking 3-days safety & security training now.
The lecturer said we can carry 5L of water with one condom(need to test it!).
But, seriously! they recommended us to carry a few since it is very light and compact and good, for really in case, we don't have anything to carry water in unpredictable situation...
