@30pics4jackiesdiamond They are a lot of fun, but you really have to be careful in the sunlight. The sun in the South is very bright and hot. It will burn your fingers in seconds. And I almost caught my deck on fire once trying to take a picture. I had only set the crystal ball on the deck for less than 5 seconds and it the wood started smoking.
Thank you! I live in England so might be safer here. But I'll bear it in mind and not keep near windows (assuming kids act on Mummy's Christmas wish list of one item!)
