Design better packaging

A little mindstorm:

Imagine yourself at the age of 70. You enter the shower to do your daily freshen-up.

As you reach the time for the hair-wash you realise that (once again!) your wife has tried out a new shampoo brand. She probably did a good bargain as you find two identical bottles on the corner shelf.

But this is a weird kind of product you say. The foam does not bubble – and it is very sticky and difficult to get off again.

Little did you know that:

1. You have to wear your glasses in the shower, or
2. You have to arrange the bottles in the right order before entering the shower, or
3. You have to get your private shelf in the shower, or
4. You should stick to a body-shampoo to avoid all confusion.
