Short Warning video ...
On this short video you can see what can happen if you dont think sharply
The idea is nice to film this hoile, but the camera man was to close the end of the tube and got hit by the ball in his face and got some minor injuries.
Luckily the injury was that minor and small. we fix the problem here at us.
Thats why we inform our players and customers that they play on ther own risk.
