A father played a prank on his kids where they had the opportunity to win $25 by getting a puzzle wrong. br br After seeing a similar Facebook video online, the dad pre-loaded the other cups with $25 before sitting the kids down and showing them which cup he puts the $5 under. br br The daughter outsmarted the father, taking a risk by choosing a cup without the $5 under it, and gained for herself $25. br br The son wasn't so lucky, having picked the cup he knew had $5 causing him to lose out on the $25. They played the game today (March 26) at their family home in Gosford, Australia.
