Robbie Keane teases Robert Jnr with the famous water bottle trick

It’s the trick that never seems to get old, and this time it’s former Republic of Ireland Captain and Tallaght native Robbie Keane who is catching out his son, Robert Junior.

The idea is you pretend to do a magic trick with a coin, placing it under an open bottle of water and then covering it with a cloth or towel.

Once you take off the cover you tell the other person the coin has disappeared and encourage them to look into the open bottle of water before squirting it in their face.

There have been several well-known instalments of the trick already, and poor Robert Junior got a face full of water when his dad set him up.
