After seeing Jalen last week in assembly doing the speed stacks with his class, we decided to buy the boys a set each. Thanks to Lisa who told me they were on sale at Toyworld (via her blog). All week the boys have been watching the DVD that comes with the set, and spending hours and hours playing with them.
I personally think I would get bored with it, but Jay loves trying to beat his personal best. He is getting really good at it.
