My first attempt split in two. You can see it here below my feet. It doesn't look big because of the distance but you can see the size of these things in the next picture and the video at the end.
This was attempt number two. It just stopped going. Click on the picture to get a better idea of the size.
The boys next to the first one that split. We ended up rolling another in between the two pieces and made a slide out of the whole thing.
This video shows me rolling the first snow ball down the hill. You can barely see my head as I work to keep it rolling. It started to take off and then just split in two. That is why you see me throwing my hands up.
