Between you and me, I bought this ball because (1) it's a good (big) size for a toddler and (2) it's more fun than a mounted globe. I am really hoping to get some educational value from it, since my son is showing some interest in maps. In fact, as my wife was inflating it, our son excitedly arrived at her feet and began yelling "Earth! Earth!" That was great.
But immediately, the horseplay ensued. I hope this ball is up to the abuse, because it's not what I intended. But... oh well. After a session of kicking, rolling, throwing and carrying "Earth!" around the house, the ball seemed no worse for wear, so we sat down for a few minutes of education.
The valve stem is at the North Pole, which our boy hasn't quite figured out how to open. Yet. Despite the cloud coverage, the continents are fairly easily discernible. He wanted to know about San Francisco Bay, which is home to us, but it's not really visible on this scale, PLUS is covered in green glow-in-the-dark splotches (the splotches don't really stick out unless I know what *should* be there). Nevertheless, we're on track to learning the continents and the oceans. If he can peg the bay area or even California at some point, that would just be bonus.
Meanwhile, I think this ball is going to get a lot more kicking than studying. Its construction isn't heavy duty, but also isn't overly thin like other beach balls I've encountered. And the seams seem sturdy enough to endure indoor play, as long as it isn't being used as an airbag or bouncy horse.
Perhaps my one disappointment is the valve isn't the "self sealing" type found on some inflatables -- the kind that won't let air escape and require a pinch to deflate.
In a nutshell, here's a dual-purpose toy I'm pretty happy with, and something I'll buy again when this one succumbs to toddler mayhem.
(Update 8/25/11) -- Call me impressed. Despite the cloud coverage and lack of any borders or labels, our 2 year old has no problem identifying San Francisco, Hawaii, Kenya of all places (a neighbor was traveling there), Australia, Antarctica, and naturally, the north pole. We've even talked extensively about earth rotating and sunsets / sunrises, easy to replicate in a dark room with a flashlight. This globe has transitioned from a play thing to a real educational experience!)
