recently i went to mamak stall to have some drinks, then i found out the restaurant hanging a disc in their restaurant's hanging by the ceiling, it's weird but i assume it was an accessories to make the restaurant look kinda pretty. Then when i paid for the drinks, i ask the owner about the disc, and the fact has been discovered. The disc will keep the flies away, at first i thought it was a bad joke, but later i realize the truth about it. How to do it? simply tie the disc with a rope, then hang it to the ceiling, then you just wait, it will work just fine. :) You guys should try it!
