UV Ball.
Â
Set up volleyball net in your hall and fit oÂne or two UV (blacklight) light bulbs up, you can get these from electrical shops. <P>
Get a large beach ball (white is good) or cover in ultra violet ink. <P>
Switch off the lights and play a five-touch rule each side as it makes a better game. <P>
It’s great if they shout out the number of touches as they go. <P>
This works better in the winter as it saves blacking out any windows.
