"Chasing Bubbles"

We switched our water feature on this morning and Bracken was very puzzled with the bubbles forming and has spent quite sometime trying to figure out where they come from. BT's have a long concentration span and seem very determined to work things out for themselves and don't give up in a hurry!
A beautiful sunny day so we are just off out to a Street Fayre this afternoon with lots going on so we will see what he makes of it!
