All the kit you need, you will probably be able to find at home already. But to have the best experience, I advise:
1 x mini ball (or kiddies football)
1 x long stretchy band (or pair of tights)
1 x loop band (or tie a pair of tights into a loop)
2 x spiky balls (or 2 soft tennis balls)
If you would like a kit posted out to you, give me a shout. They are £19 plus p+p
