My school is better than your school because the air conditioning club makes a holiday bulletin board that starts out as unassuming copper tubes spelling “Happy Holidays.” After a day or so, the tubes magically draw moisture out of the air and get all puffy and frost covered like the Tombstone Pizza sale cooler at Festival Foods.
Behold the ugly copper tubes filled with magic freezy fluid.
And after a few days, the tubes rob the surrounding air of its moisture to create these beautiful cylinders of snow.
Behold the finished work of art. On the right is the acronym for the Western air conditioning club, which stands for Air Conditioning Something Something.
