Scott Burr, a chemistry professor at Gustavus Adolphus College, in Minnesota, returned from his vacation to find his office a lot shinier than he left it.

Upon returning from his well-deserved Summer vacation, the young chemistry professor found his office had fallen victim to some really resourceful students. Everything in the office, including pens, books and even his box of Kleenex tissues were individually wrapped in aluminum foil. The students were so meticulous they even wrapped a tissue in foil and put it back in the box, for effect.

Mister Burr said this kind of pranks have become somewhat of a tradition. In previous years, students have turned his office into a pirate ship and draped his office in pink. But he admits this year’s effort really impressed him, as he has never experienced anything like this.

One of the students involved in the college prank said he and his colleagues used 10 200-foot long rolls of tin foil, to pull the whole thing of.
