Though the reason for buying these packets of Oral Rehydration Salts at my local pharmacy was lamentable, the packaging design was totally worth the 80 pesewas (about 40 cents US) I spent, absent any health purpose.
Made in Ghana for distribution in West Africa, the graphics are locally-motivated and culturally appropriate.
Directions (click on photo to see larger, more readable version) specify using a beer bottle (a standard size regionally, bigger than the usual US beer bottle) to measure the proper amount of water for mixing. To a Western mindset this is complete humor, but for local use it's right on - a normal Ghana 'kitchen' is often a space outdoors and won't include marked measuring cups, but the beer bottle is ubiquitous.
Not laughable - the injunction to use clean (i.e. uncontaminated and drinkable) water. Access to water that is free of contaminants and disease is not a given in this part of the world.
