A group of teens pulled a pretty disgusting prank.

The teenagers poured laxatives into small cans  of crushed Pringles chips, then left them out for seagulls. What comes next is you will find hilarious, or quite gross.

In a video posted on YouTube, the seagulls are seen feeding hungrily on the snacks thinking they've been given a treat.

But within minutes, the heavens open as the birds swoop around the beach,  urgently relieving themselves on the crowds below.
