This amusing video shows a gaggle of penguins chasing a reflected light shining into their enclosure.<br /><br />Roy Chowdhury, 18, was visiting the Tierpark Hagenbeck Zoo in Hamburg, Germany, when he captured the moment.<br /><br />The trio of Antarctic birds can be seen following the reflected light along the wall of their enclosure after one zoo-goer decided to tease the animals.<br /><br />The curious animals are seen running along the wall with their heads moving in unison. <br /><br />Roy, a student from Sønderborg, Denmark, said: "We found it quite entertaining! <br /><br />"We were also very surprised to see the fast reaction times and the high response of the penguins to sudden movements of the reflection. <br /><br />"We did however know that we shouldn't interfere with their behaviour too much and therefore, we were reflecting the sunlight for around a minute."
