When it rains it pours...

I love how this happens. When something happens it starts happening more often. I put up an intersting ad that I ound and then someone emailed me another ad by chance. Uncanny hey. Anyway when it rains it pours, and you better get this pun when you work out how the ad works...

Get it. The lovely people in Germany do the world such favours. (guilt reaction or whatever I don't care) They came up with an ink that becomes translucent when wet. Hence when it rains, it pours... we need these in Cape Town!
