Not sure if it's a growing trend in the US... just in my kids elementary school. The schools in our area just came back from spring break... and a few kids came back from vacation in Hawaii with them. Next thing you know it... every kid in the school has them.I'm pretty sure this trend was going on 2-4 years back (at least here in Europe). Is it just now starting in the US?
Just watched some youtubes on these. They look pretty fun. Might see if I can find one to have a go .
I really suck at it... but my kids are doing all kinds of tricks after the first day. It's amazing what tricks the kids can do with these things on YouTube. Fortunately, I have a lot of friends and family at Hawaii that pick some up for me... but my wife did see some on eBay when we were looking for them.
