What is it?

Interesting day today, we met the guy that we helped at Christmas time. He was down this way, and incredibly appreciative, so he and his wife dropped into say thanks and bought a couple of awesome gifts for the kids. The kids of course loved it, and we appreciated the gesture ;-)

Then sadly I had to shoot into work for the afternoon. A short week this week as it's Waitangi Day on Friday, and I am taking some extra time to take the kids boating with their grandparents.

But it all went well. 4 days and time for a mini-holiday!.

So, what is it? Well, all I can say is that the kids did something to see what would happen and how it would change. Adam took the shot, interesting effect eh. I have an idea as to why it occurred, but can't find an explanation exactly on Google ...
