Drench

Just checked out my twitter feed and came across this: juice brand drench has decided to create some smart vending machines, which don't take money but you have to engage in some mentally challenging games for a drink to come out...the whole idea is to promote the importance of staying hydrated, and if you are not and fail then im guessing you won't get a drink! which I suppose people would perhaps already know they were thirsty if they had gone to get a drink, and it may just end up being slightly frustrating, great idea though it does indeed do it's job!!
