T-shirt as a brick

Just went to a Microsoft lecture and got a free t-shirt. The T-shirt is packed as a cube that's 5cm x 5cm x 5cm.

In the instruction, which is a piece of paper that's packed with it, they tell you to just add water to a brick and it will give you a T-shirt. They could have made the drawing a bit clearer so that you immediately know it's unpack this cube and add water it's a funny picture though will add one later.

The lecture the gave was kinda boring it was more a way to sell the company to students. I was expecting a bit more of an in depth talk.
