Edinburgh:walking on the water

You can tell it is festival time - at every corner there's something weird and wonderful.

This "attraction" is located on top of the Tourist Information Centre! And appears to be an adult size bouncy castle with water and plastic bubbles. You go inside the bubble and "walk" on the water. Hmm.

I've started to fill in some of the gaps from our Polish holiday, do have a look if you've a minute.
