Are all bouncy balls the same? My 9 year old wants to buy a really, really bouncy ball. And it has to be a small one ... the approx. 2cm diameter type .... rather than one of the 6+ cm ones that seem to have a few more claims of superiority associated with them. He's been searching online, but the small ones all look the same. Possibly because they are all the same.
Any recommendations for a particular brand?
